Hi. I need a tutorial or giude that explains how to play backups without any modchip. I heard there was some sort of way to load and emulator to play games off your HD. Can anyone please help me out. I want to play backups without ever installing a modchip.

It's called an exploit. it's not the most relaible method of chipping your system. www.xbox-scene.com will provide you with the details.
