I've currently found a way to buffer overflow the 360 by running a messed up version of GTA San Andreas where it'll crash during loading and you cannot exit. Nothing progresses and I can't use the guide button to get back into the 360 dashboard.
I'd also like to say that Xuphorz bought me here

Also, i'd be willing to rip the files and if anyone has a way to make a patch it'd help then there wouldn't be piracy issues.
