Hacking Homebrew Removing data from a PSP ISO?

[Gaisuto]

Okay, my friend wants to have Manhunt 2 on his Memory Stick to play. It's 1.2GB, and his memory stick only has 1GB. Using a CSO compression program, it brings it down to 1GB, but it's still too big.

I hear of people taking out unnecessary data in these games to make them smaller. Anyone know how to do that?

I think CisoPlus lets you remove videos and music to make the CSO smaller.

Compressing to CSO pretty much gets rid of the uneccesary files. I think the only other way to shrink the ISO is to replace videos, music, language, and remove the update files. I haven't used that CisoPlus, but you can extract the ISO and then recompile it maually using other programs.

You can use a ripp kit or UMDgen to relink in game movies to smaller files or to remove anything else you want to.
