Xbox 360 Console NES Emulator

Ive been looking into it and haven't come across any new updates to whats been made so far. From what I know you have to play the game through your pc and flash it through your 360. I don't think there is going to be an emulator made that will work directly on the 360 due to the regualar updates that the 360 odes when its online. Though it might be possible to hack the bios and us the 360s os to run emulators just as long as you don't let Microsoft update the security. Though if you still have an old xbox, Ive been told its possible to mod it and actually install emulators to it and play them stand alone, if that helps any.
