  software on many different platforms including Windows, MacOS, Unix, MSDOS, 
  AmigaOS, etc. See http://fms.komkon.org/fMSX/ for further informations.

  PSPMSX is a port on PSP of the version 2.7.0.40 of fMSX-SDL from Vincent van Dam.

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

  The PSP part of this package is under GPL Copyright, read COPYING file for more

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-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 MSX ROM FILES
   ------------

  If you want to load rom image in your emulator, you have to put your rom file
  (with .zip, .rom, .mx1 or .mx2 file extension) on your PSP memory stick in the
  'roms' directory.

  Then, while inside PSPMSX emulator, just press SELECT to enter in 
  the emulator main menu, and then using the file selector choose one 
  rom file to load in your emulator.

  Back to the emulator window, the rom should stard automatically.

  To eject a ROM choose "Eject Rom" inside the emulator menu.

  You can use the virtual keyboard in the file requester menu to choose the
  first letter of the game you search (it might be useful when you have tons of
  games in the same folder). 

  Entering several time the same letter let you choose sequentially files
  beginning with the given letter. You can use the Run key of the virtual
  keyboard to launch the rom.

  You may use the Trigger key to swap between the two virtual keyboard panels
  (numbers & letters)


5. LOADING DISK FILES
   ------------

  If you want to load disk image in the virtual drive A or B of your emulator,
  you have to put your disk file (with .dsk file extension, or gzipped disk file
  with .dsz file extension) on your PSP memory stick in the 'disk' directory. 

  Gzipped disk files are not writable.

  You proceed as previously described for ROM files, and your disk is then
  inserted in the drive 'A' of your emulator.

  To start your disk, you have to choose the "Reset MSX" option and back to 
  the emulator window, the MSX should reboot and stard your disk automatically.

  You must eject any present rom before starting a disk, or only the 
  ROM will start instead of your disk image.

6. COMMENTS
   ------------

You can write your own comments for games using the "Comment" menu.  The first
line of your comments would then be displayed in the file requester menu while
selecting the given file name (snapshot, disk, keyboard, settings).


7. LOADING KEY MAPPING FILES
   ------------

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

  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 filename (.zip etc ...)
  then when you load this rom, 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.

  If you have saved the state of a game, then a thumbnail image will
  be displayed in the file requester while selecting any file (rom, disk,
  keyboard, settings) with game name, to help you to recognize that game later.


8. CHEAT CODE (.CHT)
   ----------

  You can use cheat codes with PSP-MSX You can add your own cheat codes in the
  cheat.txt file and then import them in the cheat menu.

  All cheat codes you have specified for a game can be save in a CHT file 
  in 'cht' folder.  Those cheat codes would then be automatically loaded
  when you start the game.

  The CHT file format is the following :
  #
  # Enable, Address, Value, Comment
  #
  1,36f,3,Cheat comment

  Using the Cheat menu you can search for modified bytes in RAM between
  current time and the last time you saved the RAM. It might be very usefull to
  find "poke" address by yourself, monitoring for example life numbers.

  To find a new "poke address" you can proceed as follow :

  Let's say you're playing "1942" and you want to find the memory
  address where "number lives" is stored.

  . Start a new game in 1942
  . Enter in the cheat menu. 
  . Choose Save Ram to save initial state of the memory. 
  . Specify the number of lives you want to find in
    "Scan Old Value" field.
    (for 1942 the initial lives number is 4)
  . Go back to the game and loose 1 life.
  . Enter in the cheat menu.
  . Specify the number of lives you want to find in
    "Scan New Value" field.
    (for 1942 the lives number is now 3)
  . In Add Cheat you have many matching Addresses
  . Then go back to the game and loose more lives
    let's say up to 0.
  . Enter in the cheat menu.
  . Specify the number of lives you want to find in
    "Scan New Value" field.
    (for 1942 the lives number is now 0)
  . In Add Cheat you have now only one matching Address
  . Specify the Poke value you want (for example 4) 
    and add the new cheat with this address / value.
  . Try this cheat while restarting a new game and see 
    if the life number is 4 or not. You will see that 
    the good address is 2D2F.

  The cheat is now activated in the cheat list 
  and you can save it using the "Save cheat" menu.

  Let's enjoy 1942 with infinite life !!
