If I were you. i'd hunt down a copy of mech assault of 007 AUF
or splinter cell PT
and use Krayzies NDURE installer
I use my old xboxen.... xboxen right? as media streamers . it's really simple to do a softmod like that and there's no point in going all out for a chip this day and age. you'll need a crossover cable though, or a way to ftp. also a memory card.
