    Triangle   L diff
    Circle     R diff

    LTrigger   Toogle with L keyboard mapping
    RTrigger   Toggle with R keyboard mapping

    Press Select           to enter in emulator main menu.
    Press Start            open/close the On-Screen keyboard

  In the main menu

    Square     Go Back to the emulator window

  The On-Screen Keyboard of "Danzel" and "Jeff Chen"

    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.

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


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.
