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

  ProSystem is the best emulator of Atari 7800 game console, 
  running on Windows system.

  PSP7800 is a port on PSP of the version v1.0 of ProSystem.

  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 fw2.x or fw1.5
  (depending of the version of your firmware) on the directory psp/game 
  (or psp/game150 if you use Dark_Alex custom firmwares).

  Put your roms files on "roms" sub-directory. 

  It has been developped on linux for Firmware 1.5 and i hope it works also
  for 2.x using the great eloader (0.99x) from http://www.noobz.eu/.

4. LOADING ROM FILES (.A78)
   ------------

  If you want to load rom images in the virtual drive of your emulator,
  you have to put your rom file (with .zip or .a78 file extension) on your PSP
  memory stick in the 'roms' directory. 

  Then, while inside Atari 7800 emulator, just press SELECT to enter in the emulator 
  main menu, choose "Load ROM" and then using the file selector choose one game 
  file to load in your emulator. Back to the emulator window, your game should 
  run automatically.


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

  For given games, the default keyboard mapping between PSP Keys and Atari 7800
  keys, is not suitable, and the game can't be played on PSP7800.

  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 rom file (.a78) then 
  when you load this rom 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.

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

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