Where to get info on various file structures?

I'm sorry if this isn't the place to ask this, but anyways...

I was wondering where I could get file structure info on various file formats, such as EBOOTs, CSOs etc. I've tried searching, but to no avail.

Basically I want to write a program which deals with them, but I don't know where to get info on the file structure... For example, I want to change files in a EBOOT, or get the thumbnail picture from a CSO.

So is there a document somewhere which explains all this?

Anyways, thanks in advance for any info! :)

EBOOT format is known, and you can check groepaz's psp docs for example. CSO is just compressed iso in which there is a UMD file structure from which you can grab the PNG of the icon.

There is some source code + headers to create/decompress CSO files in the devhook sdk.

Hey! Thanks a LOT for the info - looking into it now :)

*EDIT* Oh you guys are the best! Only looked into the PBP structure (haven't searched for CSO yet) - took me a while to find, but I got it! THANKS A LOT adrahil and ufoz!
