Hi there, this is my first post here but after reading a few of the previous posts and a few people asking about the NME chip and whether this method works, i thought the following link may be useful
http://www.team-underdog.com/howto.htmlits from the nme website giving a full Tut on how to get both program and chip to work with each other. hope this helps some people out.
The work u have done is nothing short of amazing, gj on making it nooby friendly is muchly apreicated

also i havnt been able to test this yet, just ordered my drive. Also i may sound really noobish here but when u have the firmware changed, can u still play original games on live? or do they have a way to detect it?
Thanks
