Even though the XBOX is now considered an old gaming console, there is still allot to be gained to modifying your XBOX. We only use the DUOX2 for all models V1.0 through to V1.6. This chip is rock solid, it comes with 1MB BIOS storage capacity, compare this to Aladdin mod chip which only comes with a small 256kb of memory. This makes the DUOX2 the perfect mod chip to turn your XBOX into a state of the art media centre. Not only that, the DUOX2 will also allow the hard drive to be upgraded. Store all your games on the hard drive and never need the game disk again.
