I recently picked up a Slim Xbox, and figured it may be a good idea to modify my phat xbox to run backups. I did the iExtreme flashing thing and everything is working, maybe later I'll get one of those drive emulators to run games off an external HDD...or even jtag it, though I don't want to completely disassemble it to install the Parallel port (is there a USB version?) I have seen ISOs floating around of Xbox games modified to run on the 360 via disk for those who don't have a jtag installed. I have a question, how is this done? What programs are used to take say Freedom Fighters and have it play on the 360 like its compatible?
