How To Use a Gamesave
First download Modio, by Game-Tuts, here: http://www.game-tuts.com/community/modio.php
For some games mods have been patched, so in order to use the mods you will need to go to system settings (on the xbox) then click Memory. Next Press "Y" and then click 'Clear System Cache'.
Next, you will want to go back to memory, open your hard drive, go to games and pick which game you want to mod. Then highlight your gamesave and transfer it to your usb flashdrive
Next, plug your flash drive into your PC, open Modio, open the device explorer
Now click file, and then open drive
Now, click content, then your account,then game saves
Now click on the game you have a mod for
Now drag that game save to the desktop
Now open a save
Now open the save you downloaded from the desktop or the downloads
Now click the game save that you downloaded
Now you want to copy the profile id and the device id and paste them on the notepad
Now put it on the other save (the one you uploaded from xbox).
Now rehash and resign, what this does is pretty much saves it
Next open device explorer back up, then delete the game save in there and inject the newer one
Once you inject the new one your done, just put the flash drive back into the xbox, put it back on your hard drive and start the game and your done
