- IR keyboard

You can also use IR keyboard. Edit the pspirkeyb.ini

eventually layout keyboard files in the keymap
directory.

  The following mapping is done :

  Cursor        Digital Pad

  Tab           Start
  Ctrl-W        Start

  Escape        Select

  Ctrl-C        R-trigger

In the emulator window you can use the IR keyboard
for cursor keys (but it doesn't work well).


LOADING COLECOVISION ROM FILES
------------

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

Then, while inside PSPColem 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.

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)


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

You can use cheat codes with PSP-Colem
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 Zaxxon and you want 
to find the memory address where "number lives" is stored.

. Start a new game in Zaxxon
. 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 Zaxxon the initial lives number is 4)
. Go back to the game and loose a life.
. Enter in the cheat menu. 
. Specify the number of lives you want to find in
  "Scan New Value" field.
  (for Zaxxon the lives number is now 3)
. In Add Cheat you have several matching Addresses
. Specify the Poke value you want (for example 6) 
  and add six new cheats with this address / value.
. Try them one by one to identify what is the good
  one, while restarting new games and see if the 
  life number is 4 or 6. You will see that the good
  address is 717D. You can delete all others.

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

Let's enjoy Zaxxon with infinite life !!
