INTRODUCTION

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

It has been written by Greg Stanton 
(see http://home.comcast.net/~gscottstanton/) 

PSP7800 is a port on PSP of the version v1.0 of
ProSystem, done by myself in January 2007.

Use Analog stick to choose one of the 9 squares, and
use Triangle, Square, Cross and Circle to choose one
of the 4 letters of the highlighted square.

Use LTrigger and RTrigger to see other 9 squares
figures.

- 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
for cursor keys (but it doesn't work well).


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.

  Enjoy,
