so, I haven't looked too lately, but to my knowledge the only rips of DJ Hero 2 are either incomplete, pretty crap quality, or both.
I've been thinking though, and I have a thought. but since I have neither any system that the game is for, or the resources to rip anything like that, if someone could rip it and then send me what comes from it, we could go from there. that would be awesome.

No one can rip the files from the game as they're encrypted.

well that's annoying

Actually no, they're not encrypted at all... It's just... ALOT of work that nobody wants to do. Each FSB file has to be pulled the IMG files separately, then the microsoft encoded bullshit has to be decoded to separate wav channels and then pieced back together.

There is a password on the fsb files, but it's in plain sight right in the first few bytes of the file.

EDIT: Nevermind, someone already did it. Do some searching.
