SAy I got this mod chip X-ecuterII Lite would it be best to use the bios that comes on the chip or get a new one i.e. evox. which is better? also what are the latest versions of evox and xecuter? if all i really want to do is copy games my HD and be able to turn it off and on which one should i get? I also want to be able to switch back to the original bios for Live. is this possible with just using the chip as it comes. it comes with ver. 4973. Thanks for all the help
