patching games

[HapiBuddha]

i know this must have come up in the past but i need some help from a pro.
Recently i got my box modded with a Chameleon chip and EvoX, i burned a copy of DOA3 thanks to these formums but i am having difficulty burning Amped 2. when i put it into my drive it looks line, reboots, then shows the Xbox sign like any other game, yet it then returns to the EvoX dash. Is there a tool such as ISO Craxion wich i have heard of that will make the game boot? if thats the tool then how the hell do i use it (like when do i use it, on the ripped files or the iso i made from the ripped files).
thanks for all your help
