YES, very possible, but it's illegal one thing (i never really cared if it was illegal or not) and u have to download 2-3 gig games from irc or ftp, irc is the best way to go if u don't know where to get ftp's (ftps would be higher end) but some guy i know on irc does it and he has x-lite 2.2 mod, check out
www.xbox-scene.com FULLL of usefull info and read up , u can also place extra hd's in the xbox for extra storage, he said he got 18 games on in 41 gigs , good luck with this, but do it at your own risk, i'm not responsible for you
