Also, if I missed anything, please tell me, this is my first instructable, and i want this to be as in depth as possible.
I will not go over how to FTP or make the USB controller, you can find that elsewhere.
Step 1: Materials
Splinter Cell or 007: agent under fire or Original mechassault (not a special edition)
If you have an Action replay, or way to transfer save files onto xbox, then these materials are not needed.
USB modded Xbox controller
Action replay software. (free from the action replay site, i forgot where i got it...)
Save game exploit for game of your choice (i used Ndure softmod)
there are 2 ways of connection to xbox through xbox
2 straight-through ethernet cords
2 ethernet net ports on computer. (only one if not connected to internet)
With that done and out of the way, we move onto the first step!
