Caetla Installation
===================
Download Caetla and the Caetla tools, and unzip them.
It's a good idea to copy the tools to a directory in your path.

Caetla setup takes place from a DOS prompt.

If you are not using a Comms Card at the default port number of 320,
you can use the '-p' parameter with the tools, but it's better to set
an 'environment variable' - type:
SET PORT=p
(where 'p' is the correct value for your setup - run CAEFLASH with no
parameters and you'll see a list of values for 'p',
eg. 0 for a Comms Card on port 300
    10 for an XPLORER on LPT1, etc.)
You should also insert 'SET PORT=p' in your AUTOEXEC.BAT.

You can type 'SET' to see a list of your current environment variables.

Caetla installation has 4 stages:
1. Check for compatibility
2. Backup your current ROM
3. Flash Caetla
4. Configure Caetla

1. Check for compatibility
Power off the PSX and type:
        caeflash -T      for an Action Replay or Caetla'd XPlorer:
        caeflash -T -XT  for an un-Caetla'd XPlorer:
Power on the PSX and press a key on the PC.

You'll see this: [Hardware information]
                 Hardware type : PAR1
                 EEP-ROM  MID : BF / DID : 07
                 This EEP-ROM is supported.
                 Is hardware-type right? (y/n)
Enter 'y' to continue.
Now you'll see this: [Writing test to EEP-ROM]
                     EEP-ROM : 1F01FC00 - 1F01FFFF(PAR1)
                     Would you like to test writing to this range?(y/n)
Enter 'y' to continue.

If it completes normally, your current AR ROM can be reflashed.
If not, you can't install Caetla on this Action Replay.
Most AR clones use a hacked version of Caetla anyway, so you might still be
able to use the Caetla tools with an 'un-flashable' AR.

2. Backup your current ROM
Power off the PSX and type:
        caeflash -b BACKUP.ROM      for an Action Replay or Caetla'd XPlorer
        caeflash -XT -b BACKUP.ROM  for an un-Caetla'd XPlorer
Power on the PSX.
Your current ROM will be saved to 'BACKUP.ROM' on the PC.

3. Flash Caetla
Power off the PSX and type:
        caeflash CAETLA.BIN      for an Action Replay or Caetl'd XPlorer
        caeflash -XT CAETLA.BIN  for an un-Caetla'd XPlorer
Replace 'CAETLA.BIN' with the name of the Caetla ROM eg. CAETLA.035
Power on the PSX.
If the Caetla menu is not displayed on the PSX, hold down L1+L2+R1+R2
on the pad and reset the PSX. 

4. Configure Caetla
Select PAL/NTSC:
Caetla will initially start in NTSC mode.
To change to PAL, press 'SELECT' and 'L1' on the PSX pad, move the
box on the screen to the left and press 'O'.
You can change back to NTSC by the same method.

Select Japanese/English:
Caetla will initially start in Japanese.
To change to English, press 'SELECT' and 'L2' on the PSX pad, move the
box on the screen to the left and press 'O'.

Set the hardware type:
Select "Configuration" from the Caetla main menu.
Choose "PAR/GS" for Action Replay, or "X-Plorer" in "Hardware Setting".
Return to the main menu.

To remove Caetla:
=================
Power off the PSX, and type:    caeflash BACKUP.ROM
Power on the PSX.
(Caeflash can re-flash XPlorer '.FCD' files)
