How would I go about ripping from a 360 game?

[TGE]

Why not wait for Windows 8? It's claimed that it will have the ability to read Xbox 360 disks so you can play 'em on your PC. I can't be sure though. It's just a rumor at the moment.

Sounds like bollocks to me...

With any next gen ripping-ness it's all about google and shadey links. If you can find someone who was ripped things from a 360 game it'll be useful to ask them, though that doesn't mean they'll be willing to help.

I ripped from Sonic '06 and Unleashed, so why not ask me /jk
As I said, it depends on luck. Sometimes the format has been cracked, or it's just unarchived. It always needs to be decompressed using the X360 SDK though.
