I have heard nothing but bad stories about the save backup battery on the 3-in-1. Short of replacing the battery (which I hear is pretty hard), I thought it might be prudent to regularly back up the save from it directly. Is this possible? I'm using the 3-in-1 Tool to flash the thing, and there does seem to be an option for loading .sav files to the NOR. Is it possible to pull the save file from a game on NOR and copy it? And since I'm here - how hard is it to change that battery, and what do I need to do it? Thanks in advance.
