1. yes
2. no, that's a gamesave exploit to allow the person to
temporarily get into evox and gain FTP access. This is only good if you know how to manually put the hacks in (in your case spacemaster, DON'T!!) or copy DOAXBV to the harddrive and play it with a nude hack

(don't ask me how, find out yourself... NOT FOR PEOPLE 10 AND UNDER... or anyone who finds shameless nudity offending).
go into xbins and go to \xbox\operating systems\linux\distrobutions\ltools and choose the Splinter Cell Pal exploit.
and when you get into the installer, choose UDE 1, PBL metoo (BIOS loader), and X2 49xx (i forget the last two numbers: this is the BIOS).
oh and just a heds up, don't sign your posts with "milkywaymaster". I know who you are.
