Is this for the Original Xbox or so you can play the GOD Version? Also what kind of mods are you looking for?
If you'd like I could always do it for you, I would need to re-download the game off the Marketplace though. But if you have a large USB device, like a HDD move San Andreas to it in the System Settings page and then start the game it should save to that device. Plug it into the computer and open it up, copy your save over and then download a gamesave from HERE. Resign it to your stuff (not sure if original games need resigning?) Then copy it onto your device and try that, there is also a cheat you can use for $250,000: Code: RT, RB, LT, A, Left , Down, Right, Up, Left, Down, Right, Up I could of gotten that wrong though, it may be LB not RB. But I'll download the game now anyway and if you can't do it or would like me to test it out first I would be more then happy to. EDIT: Could you post back if that works, if not I shall try myself and send you the save but it would be good for others who may have this problem in the future.
