GtkTiEmu is a program allowing a PC to emulate a TI calculator (at least the
17
TI89/92/92+ types for the moment).
18
It uses GTK+ (the Gimp ToolKit, http://www.gimp.org/gtk) for the GUI and the SDL (SimpleDirectmedia Layer) for the display.
19
It works on Linux and Windows platforms actually.
21
All link cables are supported by the link port: parallel, serial,
22
Black TI Graph Link, Gray TI Graph Link and the (fast)AVRlink.
24
GtkTiEmu is based on XTiger, the original TI emulator for Linux (see the AUTHORS file for more details) which uses the 68k emulation core from UAE (The Ultimate Amiga Emulator).
25
It also uses the libticables library.
34
o Works on 8, 16, 24/32 planes display (256, 65565, 16M/True colors)
35
o Easy to use thanks to a GUI developped with GTK+
36
o The ability to save the emulator state
37
o Full linkport emulation (all link cables, even virtual)
39
o Works with 1Mb & 2Mb ROMS, 128 or 256k memory (but FLASH Apps/OS does not work)
40
o Nice debugger (memory, breakpoints, traps, vectors, ...)
41
o Constrast emulated (Try [Alt] + [+] & [-])
42
o Useable through a Netscape/IE plugin (under development)
44
o Sreenshot of LCD or calculator in several images format (JPG/PCX/XPM/BMP)
45
o TI keyboard useable directly from PC keyboard or with the mouse on the skin (VTi's skins)

| SYSTEM REQUIREMENTS |
50
+---------------------+
52
You will need a PC Intel computer. A 100MHz processor is a minimum.
53
GtkTiEmu uses roughly 10MB of RAM.
54
Nethertheless, it is fast (it starts in 10 seconds on a PC166/64MB).
61
To run this emulator you will need a ROM dump. As this file is
62
copyrighted by Texas Instrument it will never be distributed with
63
the emulator. To get a ROM dump, you can use TiLP or any other
64
ROM dumping program. TiLP may be interessant because it can be virtually linked
66
A TI92 requires FargoII for getting a ROM dump.
68
If you want to run Fargo on the emulator, you will need to get
69
a backup, put the fargo core inside (converted with
70
"putfargo") and send it to the emulator.
77
When you launch it, GtkTiEmu take some a while for initializing it. Once you
78
have launched, you should see a window with the look of your calculator.
79
You can either click with the left button on a TI key, either press the
80
correspondant key of your PC keyboard.
82
Else, the right button of your mouse let you access a popup menu which contains
83
all you need (I hope !) for configuring/using the emulator.
90
The keyboard mapping is the same as VTi (since we use VTi's skins), the well
91
known TI emulator for Windows.
94
--------- ------------
118
Letters, Numbers, Cursormovement, F1-F8 + some others are the
119
same keys on both keyboards
124
[F10] Do a screen capture

| RIGHT BUTTON MENU |
129
+-------------------+
131
Rem: the SDL version have a small and tricky bug: you have to double-click the menuitem for activating it.
132
The right button menu give you access to the functionnalities of the emulator. If you let your mouse on the item during some while, a tooltip will appear.
133
This menu is organized as follow:
135
- Send file to GtkTiEmu: load a file and transfer it into the emulator. Not implemented yet. Instead, you will have to use the virtual link for the moment.
136
- Command shell (Linux only): display a prompt in the console for directly entering some commands.
137
- Config: load/save the current configuration in the config file (~/.gtktiemu ou gtktiemu.ini). The current state is not saved but loaded if it has been previously saved.
138
- Link options: configure the link port
139
- Enter debugger: see the DEBUGGER section further in the text
140
- Set program entry breakpoint: not implemented yet
141
- Reset calc: reset the calculator (RAM, FLASH: all !).
142
- Calculator state: save/load the current state or load the latest saved stated
144
Speed: for tuning GtkTiEmu. Only the 'Sync' item is implemented.
145
Colors: allows you to choose the number of grayscales as well as the colors
147
Keys: not implemented yet
148
- Skin for current calc: you can choose to display the emulator with a skin or only
149
the LCD display. You can also press 'Alt+Enter' for toggling the full-screen mode
150
- Screenshot: do a screenshot of the LCD display. The screenshot file is automatically incremented.
151
- RAM: dump the RAM content into a file. The file is a text file and contains
152
an hexadecimal & character dump.
154
Dump ROM: dump the ROM content into a file. The file is a text file and
155
contains an hexadecimal & character dump. Beware, this may take some time
156
and space disk for writing the file (roughly 10 MB).
157
ROM file: select a ROM image to load
158
Update file: select a TI FLASH upgrade file to load
159
Set ROM: list all available ROMs (installed in the ROMs directory) as well
160
as a lot of miscellaneous informations.
161
Convert into ROM: allows you to convert a TI's FLASH upgrade into a ROM
162
image. Useful for emulating a calculator without a ROM image.
163
Remark: the converted ROM image will not have a boot block and so you will
164
not be able to use some FLASH features.
165
- About: display the logo and the license as well as misc informations.
166
- Infos: some informations about the calc and the developper
167
- Exit and save state: save the current state and quit
168
- Exit without saving state: exit immediately without saving the curren state.
171

172
| LINKPORT EMULATION |
173
+--------------------+
175
GtkTiEmu emulates the linkport in two ways. First through a link cable
176
(hardware or virtual).
177
GtkTiEmu can communicate with the hardware (parallel, serial, ... link cable) or virtually (TiLP, VTi, another GtkTiEmu application).
179
Remark about virtual links: you have the choice between the GtkTiEmu and
180
the VTi virtual link.
181
For Windows users: the Vti virtual link allows you to make GtkTiEmu
182
communicate with VTi. It provides also a different linking method of the
183
GtkTiEmu virtual link.
184
For Linux users: the 2 possible virtual link are useable.
185
Simply choose the best or the fastest.
187
For the GtkTiEmu virtual link, the emulator must be set on the channel #0 and the linking program on the channel #1.
189
Else, GtkTiEmu can not load files directly from disk. It will be implemented later.
190
Sorry (I know that virtual linking is a bit slow) !
192
//It can also load files directly from disc and emulate the TI92
193
//protocol to load them into the emulator. This is accomplished
194
//from the commandstate (see below) with the "load" command
195
//(and also the "files" command which is perhaps less obvious).
202
It does not work in the Win32 version due to a memory bug.
204
For quickly launch the debugger, press F9. Else, you can use the right button menu.
205
The debugger allows you to monitor the code and registers, place several kind of breakpoints (addresses, traps, exceptions, data, ...) and also single step your instructions.
207
Remark: there is a popup menu available on the 'Code' and 'Memory' frames. Simply press your right button mouse for displaying it !
209
Currently, the 'Log' menu is not implemented.
216
Simply press F10 for doing a screenshot with the current options. The different options can be easily modified in the 'Screenshot options' dialog box.
217
You have the choice between several file formats: PCX, XPM, JPG and BMP (SDL/Win32 and SDL/Linux only).
219
The screenshot filename is automatically incremented whenever you do a screenshot.
226
All the informations about the command line and the configuration file format
227
(~/.gtktiemu or gtktiemu.ini) are available in:
228
- the manpage for the Linux users ('man gtktiemu'),
229
- the Manpage.txt file for the Windows users.
236
Jonas Minnberg for making (X)Tiger from which we have developped GtkTiEmu.
237
Rusty Wagner for the calculator skins.
244
- FLASH archive works but not FLASH Apps/OS
245
- X11 version seems to not start in 8 bit mode
246
- X11 & SDL version have not been tested in 32 bit mode (I wasn't be able to
249
If you find a bug, please give your:
251
- ROM version & HW type
252
- the size and color depth of your screen (Linux users can use the xdpyinfo
254
- any infos you think interessant.
255
Please report any bugs at <rlievin@mail.com>.
262
See the TODO file for more informations.
263
Nethertheless, if you like programming in GTK+, you could develop a skin editor for Linux. Mail me, you will have all my help !
