I just finished helping my bro mod his xbox. He put in a chip, and a new hard drive (120gb), and he can now play games right off the hard drive, and play n64, nes, and snes games and tons of other ...

that is really awesome. what emulators is he using for each?

I think I set him up with fce for nes, xsnesx, and a project 64 variant for n64
