1. INTRODUCTION
   ------------

  TI99Sim is a very good emulator of Texas instruments TI99 home computer
  running on Windows and Unix. The emulator faithfully imitates the TI99/4
  model (see http://www.mrousseau.org/programs/ti99sim/)

  GP2XTI99 is a port on GP2X of the version 0.1.0 of TI99Sim.

  Special thanks to Danzel and Jeff Chen for their virtual keyboard,
  and to all GP2X-SDK developpers.

3. CONTROL
   ------------

  In the TI99 emulator window, there are three different mapping 
  (standard, left trigger, and right Trigger mappings). 
  You can toggle between while playing inside the emulator using 
  the two GP2X trigger keys.

4. LOADING KEY MAPPING FILES
   ------------

  For given games, the default keyboard mapping between GP2X Keys and TI99 keys,
  is not suitable, and the game can't be played on GP2XTI99.

  To overcome the issue, 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 ...).

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

  If the keyboard filename is the same as the cartridge file (.ctg)
  then when you load this tape file, the corresponding keyboard file is 
  automatically loaded !

  You can now use the Keyboard menu and edit, load and save your
  keyboard mapping files inside the emulator. The Save option save the .kbd
  file in the kbd directory using the "Game Name" as filename. The game name
  is displayed on the right corner in the emulator menu.

  
5. COMPILATION
   ------------

  It has been developped under Linux using gcc with GP2XSDK. 
  To rebuild the homebrew run the Makefile in the src archive.
