Gaming Question: How To: Open a PsP Iso/Cso File

[KirbyPink]

So, i recently got my PsP (Whoopie freaking yay it rocks). And i installed Yu-gi-oh! GX Tag Force.
But, there is a thing bothering me. The Duel Music. It sucks. ALOT! Is there anyway i can open the file and change the music file?

Download UMDGen, the latest version is .4 or 4.
Then find the music file, and replace it with another of the same format. (not generic like mp3, idk if there's even converters)

Hm, well. This didn´t make any sense. New to this program you just said.

Well, i checked around. At least 5 times. And i can´t seem to find it. It´s either inbend in the rom. Or a file.
*fiddles around more*

Since it's a PSP game, the music is likely to be in ATRAC format if you can find it.

I´m pretty sure there isn´t a file named called music.atrac (Adaptive Transform Acoustic Coding).

Tough, i did fine the opening movie file.

*changes it to J version instead*
