I know you can rip CD's to the hard drive, but what Im doing right now is editing sounds you'd hear at a ballpark for MLB2K11 (I'll eventually release it as a mod) in-game. Iedited them to sound like they're in the park.
Anyways, there's a ton of sounds, so I figure I'd use a CD-RW to just go from team to team. Does XBox support MP3 CD's? Like Data CD's? Or would I just have to burn it as a regular CD?
