networkBoy: I do not know anything about the db that you referred to, but I do hope it is all that you theorize it to be.
Now, what if we are unable to approve xbes in the emulator... well, could we make the xbes appear approved? If it is known how the emulator verifies an xbe as one that is approved, maybe we could modify our xbes to fit the criteria for a different game or xbe that has been approved (maybe someone could make an application to do so?). Is it possible that the emulator only checks certain parts of the xbe header? As networkBoy said, the emulator can't verify every xbe by all of its code or it would have to take up a lot more space, I would assume. If this worked, maybe we could find a game that provides the most stable environment for xbox applications in general and work from there.
I apologize for not having much background knowledge on emulators and such. Also, sorry if I misunderstood anything or missed someones post regarding something I asked.
