I can't seem to find the post, but someone mentioned how to disassemble a ps3 executable somewhere, it involved using IDA and changing the executable or something. I wish I could be more specific but I don't remember.
Could someone share the method or link to the post?
I believe it was in PS3 hacks, I also believe PPC mentioned. I'm not sure if anything was mentioned about dumping from memory and I believe the post was made within the last 2 weeks. But once again, not too sure. =/
