I have found some websites a and some forums that would try to explain some issues I am not even aware, but most of them have dead links, and they keep coming with this PSF Mirror #1 (http://www.tzone.org/~llin/psf/), which is not a help, since what I am trying to rip is not even on that database.

So can anyone help with this .BGM file thing?

Managed to find a cnverter of .BGM to WAV (http://consolecopyworld.com/ps2/ps2_utils_audio.shtml) but its not working at all. :/

Same here trying to figure out the .irx files or DAT files.

Which game you want to rip ?

I think I managed to solve the problem....
but now I don't remember what I did.... :/

I will say something tomorrow-
