ok
lets get started this is my guide to modding an xbox using splinter
cell, you can use the 2 other games like mechassault or 007 agent
underfire but splinter cell is the easiest.

Needed Items:Action Replay(costs about 30 dollars), Xbox live connection, Splinter cell 1.
MAKE SURE THE GAME IS NOT A PLATINUM HITS FOR THOSE HAVE BEEN MODIFIED AND WILL NOT WORK TO INSTALL THE LINUX.

First Install the Action replay on your computer and then open it up

You want to get the linux profile for splinter cell in the community saves

Then get a linux installer from [You must be registered and logged in to see this link.]

you can pick one or i found one on the community saves its like the
first one not sure if its there for other people but worth a try

once u do all this transfer those files to the memory card then transfer to your xbox.

K after u have the transfer done launch splinter cell, go to campaign
and click on linux profile, note: u cannot run the linux profile if u
have the downloaded maps from xbox live.

once u do u should backup your system first just incase u somehow mess up so do that (recommended)
i didnt do this but eh no problems happened to me so i was lucky

everything else is pretty straight forward your decision on what version
you want i also recommend you pick evolution x for it is easier to use.

from here you can start to mod halo on the modded dashboard or watch dvd's for free without buying the pack

DO
NOT LOG ON XBOX LIVE WITH THE MODDED DASHBOARD U WILL BE BANNED FROM
XBOX LIVE PERMANANTLY MEANING THEY IP BAN YOUR XBOX, TO DISABLE THE
DASHBOARD RUN THE LINUX PROFILE AGAIN AND GO TO TURN SOFTMOD OFF.
