Original Author of XTiger

  Tiger is a TI-92 emulator for Linux/x86.  It was originally written by
  Jonas Minnberg and was closed source.  There were two versions: the SVGA
  version and an Xlib version.  Jonas Minnberg has not worked on XTiger
  for quite a while and he gave Misha Nasledov the code and permission 
  to GPL it.

Author of the PSP port version 

  Ludovic.Jacomme (ludovic.jacomme@gmail.com) also known as Zx-81

  Special thanks to WebCousin for giving me its TI92, and to SubZero
  for testing earlier versions of this emulator on 1.5 FW.

  The IR keyboard support is based on the work of Harald Fielker 
  (author of the PSP IR Keyboard Library), and the Virtual keyboard 
  is based on the Danzel code.

2. INSTALLATION

3.2 IR Keyboard control :
   ------------

You can use an IR-keyboard with PSP XTI. Personally i use a Targus Universal
Wireless keyboard, which is one of the best. 

You can edit the file pspirkeyb.ini and modify it according to your IR 
keyboard model :

# 1  - Compaq/HP foldable keyboard
# 2  - Snap'n'Type
# 5  - HP Slim keyboard
# 8  - Belkin IR (not IrDA)
# 9  - Flexis FX-100 keyboard
# 10 - Benq G250 gamepad
# 12 - Micro Innovations Foldaway keyboard
# 13 - Micro Innovations Datapad
# 14 - Compaq MicroKeyboard
# 15 - Targus Universal Wireless keyboard
# 18 - Freedom keyboard
# 19 - NOVAETS - KIS2 - IR Keyboard
# 20 - Palm Universal Wireless Keyboard
# 21 - Hama Palm IR keyboard

You can use the arrows of your keyboard to navigate through the menus. The
ENTER key is use to validate, and the Escape key to cancel.

Inside the TI-92 window, you can press TAB to return to the emulator menu. 

The key CTRL-A -> CTRL-G are mapped to F1 -> F7.


4. LOADING TI-92 APPLICATION FILES
   ------------

  You can save any TI 92 files (with .92* file extension) on your 
  PSP memory stick. Then, while inside the TI-92 emulator, just press
  simultaneously SELECT + L1 + R1, and then using the file selector 
  choose one application to load in the RAM of your emulator.

  It may happen that the file is not properly loaded, and so you have 
  to try again.

  To manage applications already loaded in your TI-92, you can use 
  the VLINK menu (activate button 2ND and press the '-' key).

  You can find many applications on http://www.ticalc.org/ and on the 
  official TI ftp site ftp://ftp.ti.com/pub/graph-ti/calc-apps/92/

5. LOADING KEY MAPPING FILES
   ------------

If you want to modify the default keyboard mapping between PSP Keys and TI-92
keys you can write your own mapping file. Using notepad for example you can
edit a file with the .kbd extension and put it in the kbd directory.

For the exact syntax of those mapping files, have a look on sample files
already presents in the kbd directory (default.kbd etc ...). (or use the save
keyboard file menu to generate a default.kbd file).

After writting such keyboard mapping file, you can load them using the
keyboard menu inside the emulator.

You can now use the Keyboard menu and edit, load and save your default
keyboard mapping file inside the emulator. 


6. COMPILATION
   ------------

  It has been developped under Linux using gcc with PSPSDK. 
  To rebuild the homebrew run the Makefile in the src archive.


7. ROM 
   ------------
  In the directory Pedrom you can find a file ti92.rom. This a ROM 
  distributed under GNU licence. It is part of the tiemu emulator 
  package.

  It is given with PSPXTI for demonstration purposes only, and
  functionalities can't be compared to TI ones !

  The rom TI-92+ v1.1 or v1.5 (other versions don't work) 
  can be found on this site http://ti83khdv.online.fr/ but you 
  have to own the original TI-92 calculator to have the legal 
  right to use it !
