i would love to see an action replay for the 360 even if it did disable acheivements while using it and i wouldn't mind if it even disabled connection to xbox live so you can't play online with codes and it doubtful the codes would work online anyway because they generally use different addresses for online and offline play so most of the offline codes wouldn't work online except for those that have online co-op play like dead island for things like infinite ammo and health where as games like battlefield 3's multiplayer likely wouldn't have infinite ammo and health.
