Does anyone know what emulator is compatible for shadow the hedgehog on RGH? I've tried a few and they won't work. (the game wont even appear in them)
You need an internal 360 hard drive to play Xbox games on an Xbox 360 console. This hard drive also needs the backwards compatibility files (Xbox emulator) installed. The game is officially backwards compatible so you can just put the disc in or play it or load it from your internal hard drive. See: Upgrade a Jtagged Xbox 360's hard drive, restore the avatars and Xbox 1 emulator - this will teach you how to setup your internal hard drive correctly on your RGH (be aware it will erase anything on it if you format it).
Ive being trying it on a 2tb usb, but it won't work still, with the emulators, but could it be a bad nand
It makes no difference if you don't have an internal hard drive setup correctly. You need an internal hard drive regardless.
