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

Caprice32 is one of the best emulator of the Amstrad 
CPC home computer series running on Windows and Unix.
The emulator faithfully imitates the CPC464, CPC664, 
and CPC6128 models.

It has been written by Ulrich Doewich.

PSPCap32 is a port on PSP of the version 4.2.0, done 
by myself in April 2006.


2. CONTROL
------------

2.1 - Virtual keyboard

In the CPC emulator window, there are three 
differents mappings (standard, left trigger,
 and right Trigger mappings). 

You can toggle between while playing inside the 
emulator using the two PSP trigger keys.

-------------------------------------

The virtual 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.

2.2 - 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 to
enter letters, special characters and digits.


3. LOADING CPC SNAPSHOT FILES
------------

Using the Linux or Windows version of Caprice32 on your
PC, you can save any snapshot files of your CPC games
or applications.

You can then save those snapshot files (with .zip or 
.sna file extension) on your PSP memory stick in the 
'snap' directory. Then, while inside CPC emulator, 
just press SELECT to enter in the emulator main menu,
and then using the file selector choose one snapshot
file to load in the RAM of your emulator.

Save state files are now saved using gzip
compression, with SNZ as file extention). It's much
faster to save or load states. You can use gzip or
7-zip to convert old SNA to SNZ.  SNA file format is
still supported for loading, so you convert your
previous saved files (or original Caprice32 files),
directly inside the emulator.


4. LOADING CPC DISK FILES
------------

If you want to load disk image in the virtual drive A 
of your emulator, you have to put your disk file 
(with .zip or .dsk file extension or gzipped disk file
with .dsz file extension) on your PSP memory 
stick in the 'disk' directory. You proceed as 
previously described for snapshot files, and your disk 
is then inserted in the drive 'A' of your emulator.  

Gzipped disk files are not writable, but they
are much faster to load (mainly on fw >= 3.80 because
memory stick access has become very very slow :
( ...
As for SNZ file, you might use 7-zip to convert .dsk
files to .dsz.

The first method to launch a game after loading a disk
file, is to set the "Disk startup" option to "full"
and to set the "Reset on startup" option to true.

When you insert a disk using the "Load disk" menu
then game will start automatically.

If you want to can set the "Disk startup" option to 
"manual", and browser yourself the content of the
disk using the "Explore disk" menu.

If you want to do all this manually, set the 
"Disk startup" option to "manual" and proceed as
explained in the following paragraphs.

To display the content of your drive, you have to use 
the virtual keyboard (press START key) and type the 
CPC command 'CAT' followed by ENTER (Triangle).
For example if you have loaded the disk file of the 
game "Green Beret" :


       CAT

You should see something like this :


       Drive A:
 user    0
       
       GBERET    .     * 15K

       140K free

You can also use directly the shortcut in the emulator 
menu (Command CAT option)
   
Then if you want to run a program GBERET that is on 
your drive 'A', you have to use the CPC command 'RUN'
as follow :


       RUN"GBERET

If the filename of the .dsk (here gberet.dsk) is also 
the name of the program you want to run (here gberet) 
then you can use directly the Command RUN" in the 
emulator menu. 


If the command to run is different from the filename 
then you can specify the proper command to RUN in the 
file run.txt, for example :


    mygame=DISC

Then, while using the Command RUM/CPM menu, the 
emulator will type RUN"DISC instead of RUN"mygame. 
Have a look the file run.txt for details about the 
syntax.

You can specify CPM games in the run.txt file using 
the following syntax:


     mygame=|CPM

Then, when using the Command RUM/CPM menu, the emulator
will use the |CPM command (instead of RUN"mygame).

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

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 game.

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

You can use cheat codes with PSP-CAP32 emulator.  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 Prehistorik2 and you want to
find the memory address where "number lives" is
stored.

. Start a new game in Prehistorik2
. 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 Prehistorik2 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 Prehistorik2 the lives number is now 3)
. In Add Cheat you have now one matching Address
  (for Prehistorik2 it's 3F30)
. Specify the Poke value you want (for example 5) 
  and add a new cheat with this address / value.

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

Restart the game and let's enjoy Prehistorik2 with
infinite life !!

7. 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).


8. LOADING KEY MAPPING FILES
------------

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 snapshot
(.sna or .snz) or  disk filename (.dsk or .dsz) then
when you load this snapshot file or this disk, 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 (snapshot, disk,
keyboard, settings) with game name, to help you to
recognize that game later.


9. SETTINGS
------------
