|Seems like the original disk would be the preference. My guess is that its a safety feature. Even if you bought the disk, the manufacturer probably set it up so that you can only play with the original disk in the system. This would prevent the possibility of someone copying it. I am sure you probably have the disk, and its just more convenient to run it from a flash disk. |
You might be able to take a flash disk and set it up as the fable disk using some sort of disk image, however if I built the game, I am guessing that I would safeguard against this as well.
