What I was referring to was modding both boxes, finding your data on the original xbox, copying it, and simply transfering the data to a modded 360.
The reason why I was tiptoing was because the only modding done to the 360 so far has no use but piracy.
Datel makes alotta wonderful gadgets, but I would sooner do it myself using modded boxes. FOR FREE.
EDIT: Asking around, I'm not sure the Action Replay thing has been sucessfully done yet.
