sacado del manual que trae el myps2 :
1. Installing & Configuring myPS2
To install myPS2 to your memory card simply transfer the following directories
and files using your favourite file manager or FTP program (Directory- and
filenames are case sensitive).
/boot/
/fonts/
/language/
/shoutcast/
/skins/
MYPS2.ELF
CONFIG.DAT
After you have transfered the files just launch the MYPS2.ELF executable
from your bootlauncher application.
If you want to install the program to your HDD you must add two entries
to the CONFIG.DAT file:
hdd_boot_part = hdd0:PARTITION
hdd_boot_path = /PROGRAMS/MYPS2/
hdd_boot_part is the name of the partition you have myPS2 installed on.
hdd_boot_path is the path of the directory you have myPS2 installed in.
You can also run the program from CD. To do this burn the files on CD along
with the SYSTEM.CNF file. You should also add a dummy file to the compilation.
It doesn't matter what this file is, just make sure it's at least 30 MB.
