* Compute the T_f transform modulo n.
*
* Because only one quarter of the possible hashes can be signed with
* a given key, we need to transform the hash. First, we want to
* ensure that the result is nonzero, so we shift the hash by 8 bits
* and add a 1 to the end. The resulting number is called m'.
*
* Second, we want to multiply it by a number k whose Legendre symbols
* (k|p) and (k|q) are known, so that (km'|p) = (k|p)(m'|p) = 1 and
* (km'|q) = (k|q)(km'|q) = 1. Since we need both to be true
* simultaneously, regardless of the values of (m'|p) and (m'|q), we
* clearly need four possible values of k.
*
* As it happens, TI's keys all follow a precise format: they all have
* p === 3 and q === 7 (mod 8). As a result, we know that
*
* (-1|p) = (-1|q) = -1
*
* (2|p) = -1, (2|q) = 1
*
* So TI has defined the following transformation functions:
*
* T_0(x) = -2x'
* T_1(x) = -x'
* T_2(x) = x'
* T_3(x) = 2x'
*
* where x' = 256x + 1.
*
* In the usual case of p === 3 and q === 7 (mod 8), then, two of the
* possible (T_f(m)|p) will equal 1:
*
* If (m'|p) = 1, then (T_0(m)|p) = (T_2(m)|p) = 1.
* If (m'|p) = -1, then (T_1(m)|p) = (T_3(m)|p) = 1.
*
* Two of the possible (T_f(m)|q) will equal 1:
*
* If (m'|q) = 1, then (T_2(m)|q) = (T_3(m)|q) = 1.
* If (m'|q) = -1, then (T_0(m)|q) = (T_1(m)|q) = 1.
*
* Thus we can choose exactly one f value with
* (T_f(m)|p) = (T_f(m)|q) = 1.
*
* If r === 5 (mod 8) is a prime, (-1|r) = 1, while (2|r) = -1. Thus
* a similar logic holds:
*
* If (m'|r) = 1, then (T_1(m)|r) = (T_2(m)|r) = 1.
* If (m'|r) = -1, then (T_0(m)|r) = (T_3(m)|r) = 1.
*
* So if {p,q} === {3,5}, {5,7}, or {3,7} (mod 8), given any m, we can
* pick an f with (T_f(m)|p) = (T_f(m)|q) = 1.

/* This file only contains the changelog for the gui/doc/data, some things could be missing (core changes...)*/
/* This changelog was started when I started to work on TilEm2 */
/* contra-sh :
* ---18/08/09---
* - Draw the TI83
* - Copy from testemu.c : Create the savname, Open the Rom, Get the model, Draw the lcdscreen (no animation for the moment)
* - Function event OnDestroy
* - Modification of the Makefile (I hope it's good !? If you can control this... thx)
* - LEARNING HOW COMMIT !! :D
* ---19/08/09---
* - New structure TilemCalcSkin : define the different filenames for the SkinSet (4 pieces).
* - Draw the other models _automatically_ . ;D
* ---20/08/09---
* - Create skin.c
* - Create gui.h (equivalent of tilem.h for the gui directory)
* - Move the code struct in gui.h and TilemCalcSkin* tilem_guess_skin_set(TilemCalc* calc) into skin.c (only one call in the main file to define the skin set) ;D
* - Detect a keyboard event (function keyboard_event() in skin.c actually).No treatment.
* - Detect an event click on mouse
* ---21/08/09---
* - Get the x and y values when click on mouse (now it will be easy to know how key is click on the pixmap, todo in priority : detect right click)
* ---24/08/09---
* - Detect right click.
* ---26/08/09---
* - New function : TilemKeyMap* tilem_guess_key_map(int id).Choose a TilemKeyMap with an id given in parameter.
* ---27/08/09---
* - Extract the choice of the key_map from the mouse_event function.Execute only one time and it's more properly (and it will be easier to add the possibility to manage many skins and many keymaps).
* ---01/09/09---
* - Choose automatically the key_list. The TilemKeyList is already included in the TilemKeyMap structure...
* - New structure TilemKeyCoord (old TilemKeyMap).TilemKeyMap already contains TilemKeyCoord and TilemKeyList...
* ---08/09/09---
* - New function tilem_set_coord to change the keypad coord.
* - New file event.c to group the GDKevent handling.
* - New function tilem_set_skin to change the skin.
* ---10/09/09---
* - Add the right click menu :D (0 signal connected without OnDestroy).Largely inspired from Tilem 0.973 and http://www.linux-france.org/article/devl/gtk/gtk_tut-11.html was a great inspiration too.
* ---21/09/09---
* - Aouch I had seen that the left click doesn't work now! Problem : two callback for the only one button_press_event. (sorry for this version...)
* ---22/09/09---
* - Correction : only one callback now. mouse_event contains the create_menu and the gtk_menu_popup. (lot of time was spent on this problem)*
* ---23/09/09---
* - Change TilemKeyCoord to the 82 stats skin.Change Event.c too.
* ---06/10/09---
* - Beginning the correction : change the method for testing coordinates clicks (one line now) . The coordinates will be imported from a file soon.
* ---20/11/09---
* - After 1 week to learn Tiemu skin format...I have made my own Tilem skin Generator.Inspired from skinedit.It just generate compatible file with 0 coordinates values, and an default lcd coordinates.Not really necessary but very useful for testing and for learning how this f****** skin format works.It will be called skintool for the moment.
* ---27/11/09---
* - After blocking a problem for a week grrr... I succeed to adapt the TiEmu skinloader to TilEm (skinops.c and skinops.h).Little modifications
* ---28/11/09---
* - The mouse_event function now use a SKIN_INFOS struct. So delete TilemKeyCoord struct.
* ---02/12/09---
* - Add a GtkFileSelection (access by right click menu) and try to load another skin with this method.
* ---03/12/09---
* - Create a GLOBAL_SKIN_INFOS that contains a KEY_LIST struct (old TilemKeyList) and a SKIN_INFOS struct.
* ---04/12/09---
* - Delete the TilemKeyCoord, TilemKeyMap, TilemCalcSkin and TilemKeyList structs...
* ---05/12/09---
* - The GtkWidget *pWindow creation was moved from testemu2.c to event.c .The function is called GtkWidget* Draw_Screen(GLOBAL_SKIN_INFOS *gsi);
* ---07/12/09---
* - New feature : TilEm could load a skin by the right_click_menu ! It use GtkWidget* ReDraw_Screen(GLOBAL_SKIN_INFOS *gsi) in event.c. WAOUH !
* ---08/12/09---
* - Move Draw_Screen, ReDraw_Screen and create_menus in a new screen.c file. Change Makefile.
* ---14/12/09---
* - New feature : add a popup rom type selector (radio button) at the start of tilem. Showed but not used for the moment.
* - Connect the thread (no animation yet). Thanks to the "battle programming" 's spirit (hey bob ^^)
* ---18/12/09---
* - Launch the interactivity with emulation core. Could print into the draw area.
* ---09/03/10---
* - Restart working on this program ;D
* ---11/03/10---
* - I finally succeeded to connect the core. To print something into the lcd screen ! WahoOO ! This day is a great day !
* - I succeded to type numbers etc...
* - And now it works very well !! (the "button-release-event" is not catched by pWindow but by pLayout)
* ---15/03/10---
* - Create the scan_click function.Return wich keys was clicked.Print debug infos.
* - Create the debuginfos.h to group the ifdef for debugging. (different level and different type of debug msg)
* ---17/03/10---
* - Create the rom_choose_popup function to replace choose_rom_type.It use GtkDialog instead of GtkWindow.
* - rom_choose_popup _freeze_ the system... and get wich radio button is selected. So it will be easy to create the good emu.calc (and choose the default skin).
* ---18/03/10---
* - Resize the (printed) lcd area (gsi->emu->lcdwin) to fit(perfectly) into the skin.
* - Replace a lot of printf by D****_L*_A* to easily switch what debug infos were printed.
* - Try to make a nice debugging output (frames in ASCII ^^) :p
* - WahooOO , load a skin works perfectly.You can easily change skin _while running_, no error, no warning.
* - Could load automatically the good skin and run the good core using the choose_rom_popup() function and choose_skin_filename() function.
* ---30/03/10---
* - Create skin for following models : 73, 81, 82, 83+ and 84+.
* - Fix bug in tool.c .Modification of tool.c to create radio button more properly.
* ---31/03/10---
* - Create skin for following model : 83 . Based on my own calc (take a foto with my iphone 3GS :D)
* ---01/04/10---
* - New feature : Save calc state and load state. State are stored in a separate dir called sav/ . (using benjamin 's function)
* - New feature : Change view to see only the lcd. I finally choose to add it into a GtkLayout. So you can maximize it, but there was problem with add_event.
* ---02/04/10---
* - Add popup function to just print error message.You must give the message and gsi as parameter, and it run a modal dialog.
* - Some cleaning.
* ---23/04/10---
* - Add config.c file to manage config.dat (create, read, modif etc...).
* ---31/05/10---
* - Start from scratch a totally new debugger :D.Just draw button with nice GtkImages.Actually in essai2 directory.
* - Get and resize pixmaps (png) to 36 * 36 pixels for the debugger.
* ---01/06/10---
* - Add the debugger to tilem. Load registers values.
* - Add a new feature : switch the top level window "borderless".It can be switch by clicking on right click menu entry.
* ---02/06/10---
* - Create the GtkTreeView (debugger).
* - Refresh register on click.
* ---05/08/10---
* - More than one month without working on tilem...Only commit old modif, and skn/README file.
* - Refresh stack on click (number of entry is correct but value not)
* ---06/08/10---
* - Working on a new system of configuration file.The config.dat is now a binary file (as .skn but totally differennt). At start, a CONFIG_INFOS struct is filling, then when clicking on right menu, this struct is modified, then when you stop tilem, config.dat is writed on disc.
* ---09/08/10---
* - Correction of the SEG_FAULT (never use sizeof(char*) inside malloc, strlen(char*) is better :P).
* ---10/08/10---
* - Working on a new config file called romconfig.dat (inspired from config.dat) using to do not ask for model each time tilem is started.
* - It works :D
* ---12/08/10---
* - NEW feature : Can load a file using libticalcs2 (inspired from the wokr of Benjamin Moody). Basically it works, but it's not OK. (many bugs)
* - Drop the deprecated GtkFileSelection.Use GtkFileChooser instead. :)
* ---13/08/10---
* - NEW feature : Add the screenshot feature.
* ---17/08/10---
* - Change the ti84plus.skn (old was really ugly).
* - Add doc/ directory : add romconfig_file_format.txt and skinconfig_file_format.txt.
* ---18/08/10---
* - Correct the bug in link.c (unlock mutex ...)
* - Start working on macro handling : Always do the same things to load and launch a file into an emulator become quickly noisy for the programmer (1 time, 10 times, 30 times, 50 times...argh!). Simply record a sequence and play it to test a program, this is one solution. (feature request from Guillaume Hoffman gh@gmail.com).
* ---19/08/10---
* - The macro feature works including loading file (very important). The implementation is very basic (record and read a text file) so many bug could (should?) appear. But I wait to see how it will be use.
* ---20/08/10--
* - Better implementation of GtkFileChooser (to be cleaner).
* - Some work on macro (no seg fault now ^^).
* - Add a Save state... entry in right click menu (no need to stop tilem to save state)
* - Add a Play macro with GtkFileChooser (to play another macro than play.txt).
* - Fix minor bug in GtkFileChooser (forget to init a char* to NULL).
* ---23/08/10---
* - Add a new args handler using getop library (add -m for macro and -k for skin).
* ---06/09/10---
* - NEW feature : could print the lcd content into the terminal. So useless but so funny ;) (feature request from Guillaume Hoffman).
* - The output is saved into a file called lcd_content.txt.
* ---08/09/10---
* - Could choose wich char to display. This not really works as I want, but this is not a really important feature (works 1/2)
* - Add an option at startup (-l). Could now start in skinless mode.
* ---04/10/10---
* - Start working on animated gif. Some research on GIF file format. Oops it will be hard, file is encoded (!).
* ---09/10/10---
* - Creation of 1 little static gif file seems working, but always no LZW encoding.
* ---12/10/10---
* - Finally I decided to use external source to encode the pix data.I use a file called "gifencode.c" by Hans Dinsen-Hansen and Michael A. Mayer. And it works !!!
* ---14/10/10---
* - It works ! It works !!! Tilem2 is now able to generate animated gif, functions are currently working (but totally buggy) and it successfully create animated gif :)
* - Need to be integrated (and lot of debug).I commit it just to save it...Wait another commit to really use this feature :P
* ---01/02/11---
* - Starting to work on a new config file using glibc to do not hard code keypad values.
* - And it works !!!! (but only load one keypad model currently)
* - Add the other models into keylist.ini (but the content is completely false). Change scan_click method (correct a bug) to use kp->nb_of_buttons. Only need to give correct value into the keylist.ini file. For the rest it's seems ok.
* ---07/02/11---
* - Start to work on config.ini. A new generation config file using GKeyFile library (glib). Add some work in essai4 directory.
* ---08/02/11---
* - Remove romconfig.c romconfig.h config.c config.h (handle binary config file). Remove ROM_CONFIG_INFOS and CONFIG_INFOS from gsi.
* - Add a new config.c and config.h file to handle config (last rom used, default skin to load, etc...). It uses glib GKeyFile library.
* - Fix the macro bug pointed by Benjamin.
* ---15/02/11---
* - Replace correct copyright/licence informations into skinops.* .Sorry for the inconvenience.
* ---16/02/11---
* - Fix an important mistake into the gif creator function (palette should be before gif frame information).
* ---18/02/11---
* - Connect a timer to automatically add frame to a animated screenshot (using screenshot box).
* ---14/03/11---
* - Improve default skin choice.
* - Define the skin's basedir into the config.ini. Add a universal getter into config.c .
* ---19/03/11---
* - Add a bouncy progress bar to show the link status (send file).
* - Add a file saver.
* - Create a new TilemCmdlineArgs structure.
* ---07/04/11---
* - Drop deprecated gtkitemfactory
* - Prepare GT3 migration
* ---10/04/11---
* - Benjamin add a configure script and all associated things (Makefile.in, config.h etc...).
* - Fix dependency and a lot of cleaning.
* - Benjamin add a lot of function to handle data directory.
* ---13/04/11---
* - Completely refactoring the screenshot window. New preview possibility.
* - Add some cool features for screenshot menu (replay from file, preview animation, preview screenshot, 2 gtkfilechooserbutton, change default folders etc...).
* - Remove old pix directory.
* - Benjamin begins to work on new debugger.Add a menu, some basic actions.
* ---15/04/11---
* - Benjamin add a set of function to handle user defined icons. A lot of improvement on the debugger (add step action, pause).
* - Use tilem logo as default background in the screenshot menu, add some pix into the shared data directory.
* - Remove old debugger pix.
* - Add GtkSpinnerAnimation in the screenshot menu. Improve look and feel (fix fill/expand properties for the box, size of the widgets etc...).
* ---17/04/11---
* - Benjamin add a ti83p symbol file which allow to replace flag values by theirs labels in the debugger (and more other things). Debugger looks like very good.
* ---19/04/11---
* - I've added a ti83 symbol file (but it could contains some mistakes...). Flags are correctly printed for my loved ti83 regular ;)
* ---27/04/11---
* - Root window size could be forced (but the ratio could be strand if you specify stanges values ... Because ration is calculated on the start width and heigth).
* ---02/05/11---
* - Add the icons for the right click menu (stock icons currently).
* - Export all menu related code in a separate file called menu.c. It could maybe be done by UI in the future, but it works fine as it for the moment ;)
* - Add drag and drop support for loading files :) :) :) :) :) (code is currently really ugly)
* ---09/05/11---
* - Create a new TilemGuiStateFlags structure ot group the running state of the gui (skinless, recording macro, etc...) and export it into TilemCalcEmu instead GLOBAL_SKIN_INFOS.
* - Completely remove GLOBAL_SKIN_INFOS structure from tilem2.
* ---10/05/11---

* ---12/05/11---
* - I finally found what's wrong in my gif creation. So I can do multicolor gif now.
* ---14/05/11---
* - We have finally completely reorganized the code to drop GLOBAL_SKIN_INFOS, and rename a lot of stuff including files (emuwin instead screen by example).
* - Benjamin have imported his nice filedlg functions (filedlg.c) from flashbook ui (see it on SF.net). Now use it for the entire code.
* ---14/05/11---
* - Refactor the gif creation to separate clearly which value can be modified, which one are magic number etc... Create separate functions for each task.
* - Benjamin begins to work on animation (instead of writing file while recording it). It provides a wonderful objects to handle screenshot.
* ---15/05/11---
* - Add a doxyfile for generating documentation including callgraphs.
* - Improvement to keybindings (Benjamin).
* ---16/05/11---

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<http://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read
<http://www.gnu.org/philosophy/why-not-lgpl.html>.

Installing TilEm
------------------
To compile TilEm, you will need:
* a standard C compiler
* the GTK+ library, version 2.6.0 or later
* the libticalcs2 library (part of the TiLP project), and its
dependencies (libticables2, libtifiles2, and libticonv)
Some OS distributions package the "development files" separately from
the libraries themselves; you need both. If you are using Debian (or
a related distribution, such as Ubuntu or Mint), install the packages
'build-essential', 'libticalcs-dev', and 'libgtk2.0-dev'.
If these packages aren't available from your package manager, you'll
need to compile them yourself; see the TiLP website for more
information (http://lpg.ticalc.org/prj_tilp/).
Mac OS X has not been tested by the TilEm team, but if TiLP works,
TilEm should, too. Please let us know if you do get it to work.
Once the above dependencies are installed, open a terminal and 'cd' to
the directory containing this INSTALL file. Then run
./configure
which will check whether you have all of the necessary software
installed, and figure out how to compile TilEm for your particular
system. If configure is successful, you can then run
make
to compile TilEm. Finally, you can run
sudo make install
to install it (or run 'make install' as the superuser.) The program
will be installed in '/usr/local/bin/', and data files will be
installed in '/usr/local/share/tilem2/'. Alternatively, you can run
make install-home
to install TilEm in your own home directory ('$HOME/bin/', with data
files stored in '$HOME/.local/share/tilem2/'), which does not require
superuser privileges. (If $HOME/bin didn't exist already, you might
have to run 'export PATH=$HOME/bin:$PATH', or log out and log back in,
before running TilEm.)
Once TilEm is installed, start it by running 'tilem2', or through your
system's applications menu.

KEYBOARD BINDINGS
This list shows the default keyboard controls for TilEm. You can
modify these, if you like, by editing 'keybindings.ini'. (Place the
modified version of keybindings.ini in your TilEm configuration
directory - $HOME/.config/tilem2/ on Unix, or
$PROFILE\Local Settings\Application Data\tilem2 on Windows.)
In the following list:
S = Shift
C = Control
↑ = 2nd
α = Alpha
² in the TI-82/83 column indicates that the key is only for the TI-82.
³ indicates that it is only for the TI-83/TI-83 Plus/TI-84 Plus.

For the TI-83 Plus and TI-84 Plus, in addition to the keys listed
above for the TI-83, pressing Shift+letter while Caps Lock is enabled
will type a lowercase letter (Alpha, Alpha, letter.) Lowercase mode
will need to be enabled on the calculator for this to work; it's not
enabled by default, but there are many assembly programs that can do
so.

Version History
-----------------
2012-06-07 -- version 2.0
This is the first official release of the "new" TilEm. Much of the
old TilEm code has been rewritten, and there are many improvements
(and probably some new bugs.)
Please note, if you have used older versions of TilEm:
* Your existing ROM files and settings in ~/.TilEm will not be
used (in fact, you can keep TilEm 0.97x installed alongside
TilEm 2.0 if you wish.) TilEm 2.0 no longer uses a "library" of
ROM files; you can store ROM files anywhere you like.
* TilEm 2.0 uses a new format for calculator state (SAV) files.
State files created by TilEm 0.97x can be loaded by TilEm 2.0,
but if you then save the state, it will be stored in the new
format, which older versions of TilEm will not support.
New features and bugs fixed since version 0.975 include:
* All code that was covered by the Z80em license has been removed.
* Support for the TI-81 (both hardware versions) and TI-76.fr, and
experimental support for the TI-Nspire's TI-84 Plus emulation
mode.
* Many hardware emulation improvements for all calculator models.
In particular, major improvements have been made concerning Z80
interrupts, timers, the LCD driver, and the link port.
* The emulator window uses TiEmu-format skin files.
* Greatly improved grayscale emulation.
* Commands for saving still screenshots (in PNG, BMP, JPEG, or GIF
format) and animations (GIF format only.)
* Keypad macros can be recorded and replayed.
* Programs and/or ROM files can be loaded from the command line.
* Link I/O uses libticalcs2, which allows all types of variables,
as well as Flash apps and OSes, to be transferred through the
link port. For the TI-81, PRG files can be transferred to and
from the calculator memory directly.
* TilEm does not consume 100% of the host CPU when idle.
* Improved disassembler (macros; distinct "labels" and "romcalls";
named IY flags.)
* The debugger offers a "Finish Subroutine" command. In addition,
the "Step Over" command behaves more sensibly.
* Breakpoints can be set on absolute memory addresses, and on Z80
opcodes.
* Many minor improvements.
Features of 0.975 that are not yet supported in TilEm 2.0 include:
* External link cables.
* Custom symbol files in the disassembler.
* Program counter history tracking.
Most of the new code is due to Benjamin Moody (floppusmaximus) and
Thibault Duponchelle (contra-sh). See THANKS for a full list of
contributors.

of 2012), and attempts to reproduce the behavior of the original
calculator hardware as faithfully as possible.
In addition, TilEm can emulate the TI-Nspire's virtual TI-84 Plus
mode. This is currently experimental, and some programs may not work
correctly.
TilEm runs on the X Window System on GNU/Linux and other Unix-like
platforms, as well as on Microsoft Windows, and any other platform
supported by the GTK+ library.
Installation
--------------
Packages for Microsoft Windows are available from the TilEm project
website (http://lpg.ticalc.org/prj_tilem/). For other platforms, you
will need to compile TilEm from source; please see the file 'INSTALL'
in the source package.
Using TilEm
-------------
TilEm requires a copy of the operating system from the calculator
model(s) you wish to emulate. This file is called a "ROM image",
since the calculator OS was traditionally stored in Read-Only Memory.
ROM images are copyrighted by TI and may not be distributed without
permission. See the TilEm User's Manual for more information about
how to create a ROM image.
The main TilEm window shows an image of the calculator (if possible -
we are still missing background images for a few models.) Clicking
with the left mouse button presses a key; clicking with the middle
button presses a key and holds it down. Clicking with the right
button, or pressing Shift+F10, opens the menu.
When you run TilEm for the first time, it will ask you to select a ROM
image to use. The file you select will be used by default the next
time you run TilEm. You can switch to a different ROM image by
right-clicking and selecting "Open Calculator".
The state of the emulated calculator is not saved by default; to save
the state, right-click and select "Save Calculator". The state is
saved to a ".sav" file, stored in the same directory as the ROM image.
You can send program and variable files to the emulated calculator,
either by dragging and dropping them from your file manager, or by
right-clicking and selecting "Send File". To retrieve program or
variable files from the calculator, select "Receive File".
Other features of TilEm include:
- A debugger for assembly programs
- Capturing screenshots, both normal and animated
- Recording and replaying keystroke macros
For more information, see the TilEm User's Manual:
http://lpg.ticalc.org/prj_tilem2/doc.html
About this program
--------------------
Many people deserve credit for helping to make this program possible.
See the file 'THANKS'.
This program is free software, which means that you are allowed to
modify it, and to distribute it (or your modified version) to others.
When you received this program, you should also have been offered a
complete copy of its source code. For more information, see the file
'COPYING'.
You can contact the authors at <tilem-devel@lists.sourceforge.net>.
Please let us know of any problems you encounter, or ideas for how we
could make TilEm better.

Thanks
--------
The current maintainers of TilEm are Thibault Duponchelle and Benjamin
Moody, but many other people have played a part in making this program
possible.
The original TilEm was written in 2001 by Julien Solignac. The
current version is partially based on the original, but large portions
have been rewritten, starting in 2009, by Benjamin Moody and Thibault
Duponchelle. Portions of the hardware emulation code are also due to
Luc Bruant.
The code for reading skin files is based on code from TiEmu, written
by Julien Blache. The GIF compression code is based on whirlgif,
written by Hans Dinsen-Hansen and Michael A. Mayer.
Thanks to Claude Clerc for the photo of his TI-83 Plus, and to Danilo
Šegan for the photo of his TI-86, which we have used as skins. Thanks
to Scott Zeid for the design of the program icon.
TilEm uses the TiLP libraries (libticalcs2, libticables2, libtifiles2,
and libticonv) to send and receive variables. Thanks are due to the
current maintainer of TiLP, Lionel Debroux, for his assistance, as
well as to all of the past maintainers of TiLP, including Romain
Liévin, Kevin Kofler, and Julien Blache.
Finally, this program would never have been possible without the
efforts of countless programmers and researchers over the years to
discover and document the inner workings of the calculator hardware.
The following people deserve special recognition for their research:
Randy Compton, Tijl Coosemans, Brian Coventry, Dan Eble, Dan
Englender, Dines Justesen, Julien Lasson, Mattias Lindqvist, James
Montelongo, Michael Vincent, Brandon Wilson, and Joerg Woerner.
(Thibault) In addition of above:
Thanks to Michael Nock and Guillaume Hoffman for testing, feature request and encouragement.
Thanks to Xavier Andreani for his encouragement.

** About the format : **
When I started to work on tilem 2, I firstly decided to use the old tilem format (4 pixs around a lcd).
But that's not a good idea, and the new skin creation is too hard like this ... :(
Finally, we (with Benjamin) have choosen the Tiemu skin format:
This format consists in a binary file containing skin information (author, name, model, size etc...) and in the second part :the image data.
With this format, it becomes really simple and fun to create a skin.
Tiemu Skinedit works perfectly for tilem 2 (how do you think I 've created these "officials skins :P).
I hope this new format will pleased to you.
Thank you Julien Blache for his help and his authorization to use Tiemu skin format and skinops.c/skinops.h files.
Thank you Romain Lievin too.
** About the image source : **
To find free files to generate skins is not so easy :|
A part was found on wikimedia (god bless wikimedia)
Some other are created and donated by tilem2 users :)
Some other are just my own calc.
For the source of the pictures :
ti81.skn = GFDL wikimedia.commons
ti82.skn = GFDL wikimedia.commons
TI82stats.skn = GFDL wikimedia.commons
ti83.skn = My TI83 !!!
ti83p.skn = GFDL wikimedia.commons
ti83pfr.skn = GPL v3+ given by Claude Clerc (aka claudiux). It's his calc. Thanks to him !!!
ti84p.skn = My TI84plus !!!
ti84p2.skn = Mine.
ti86.skn = LGPL v2.1. Picture given by Danilo Segan. I've resized with the gimp and I've done the skin (the skin given by Danilo was perfect but too big).Thanks to him !!!
