Hi everyone, just signed up.

Yesterday, my Gameshark v3.2 cartridge arrived. It's a second-hand device, so it didn't come without its fair dose of issues (black and white screen, freezes). Besides that, it works 'fine'. But when I try to save my game (Yu-Gi-Oh: Forbidden Memories) with my cartridge inserted and cheats enabled the game won't let me, even though there are no save files on the memory card - a message pops up saying that there aren't enough memory blocks available. What should I do?
