I had my r4 do something wierd (it hung, might be time to clean the contacts) tonight during Phoniex Wright game on the bus and I got pissed and turned it off during a save. Guess what it corrupted the save, fortanetly it was just after a trial so I found a replacement easily. But how to convert.

Well this site seems to be able to convert all save types easily, So it might be worth checking out if you are looking for a save converter.
