this is probably a really dumb question, but I wonder if it would be possible to put a game on a hard drive with the same file system that xbox game disks use then connecting the hard drive where the DVD drive usually goes, but with the yellow dvd power cord still attached to the DVD drive, and with an xbox game in the dvd drive. The dvd drive would tell the xbox that there is a game in the DVD drive, but then when it goes to read the DVD, it would read the hard drive instead of the DVD drive.
