  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/)

  PSPTI99 is a port on PSP of the version 0.1.0 of TI99Sim.

  Special thanks to Danzel and Jeff Chen for their virtual keyboard,
  and to all PSPSDK developpers.

  This package is under GPL Copyright, read COPYING file for
  more information about it.


2. INSTALLATION
   ------------

  Unzip the zip file, and copy the content of the directory fw3.x or fw1.5
  (depending of the version of your firmware) on the psp/game, psp/game150,
  or psp/game3xx if you use custom firmware 3.xx-OE.

  (standard, left trigger, and right Trigger mappings). 
  You can toggle between while playing inside the emulator using 
  the two PSP trigger keys.

    of the 4 letters of the highlighted square.

3.2 - IR keyboard

  You can also use IR keyboard. Edit the pspirkeyb.ini file
  to specify your IR keyboard model, and modify eventually
  layout keyboard files in the keymap directory.

  The following mapping is done :

  IR-keyboard   PSP

  Cursor        Digital Pad

  Tab           Start
  Ctrl-W        Start

  Escape        Select
  Ctrl-Q        Select

  Ctrl-E        Triangle
  Ctrl-X        Cross
  Ctrl-S        Square
  Ctrl-F        Circle
  Ctrl-Z        L-trigger
  Ctrl-C        R-trigger

  In the emulator window you can use the IR keyboard to
  enter letters, special characters and digits.


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

  For given games, the default keyboard mapping between PSP Keys and TI99 keys,
  is not suitable, and the game can't be played on PSPTI99.

  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.

  
7. COMPILATION
   ------------

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