I was trying to add cheats to my Mario Golf Advance game, so what I did was back up the .sav, and then deleted the ROM and .sav off the memory card, and put the new one on. It didn't work, so I wanted to put my old one back on, but when I repatched the rom and switched around the .sav files, I can't get it to work, I get the ask;daslkasjh Nintendo logo upon booting the game. How do I fix this?
