Have encountered a problem with my DK64 cartridge - every so often I'll turn the game/system on and all the saved files will have erased. A real pain considering it's like having to play four games in one given the playable characters.
Did a bit of research and DK64 doesn't use the battery system to save, so it's not as easy as simply replacing the battery inside the cartridge?
Is it fixable or would I need to buy a new cartridge altogether?
Thanks in advance for your help.
