Maximo - Ghosts to Glory PS2 files

[Andre Romhacker]

A friend of mine wants me to try to make a translation for Maximo - Ghosts to Glory version PS2.
I have not found anything in the ISO that explicitly refers to it as text, (filename, folder).

I want to know if there is a way to open or extract files from this game,
it has several formats. I left a sample of them.

Sample.rar

I suspect that prt, psx and tex are just image with a small 32 bytes header.
prs sounds like a known extension but I don't know, the magic is 0xc0defeed.
While for bef use this script:
