Nobody can make someone else's save work on your console but you. If you want to try it, you'll need the new save and a save from your console. On the first screen where it says compatibility click on the first button and point it to the save you want to use. Click the second button and point it to the save from your console. Click the 3rd button to make the change and save the new param.sfo. You then copy the save you want to use to your console. You're going to have problems using save files from updated versions of FFXIII-2 if you're on TB firmware since you can't update the game. You'll need to find a savefile from another TB user or one from someone who just hasn't updated their game
Fiery the angels fell. Deep thunder rolled around their shoulders... burning with the fires of Orc.
