For the members familiar with N64 I have a problem maybe someone can help. Last night I was playing the greatest video game ever "Perfect Dark," and suddenly all memory in the game erased. The game works fine but all my records and agents are erased. This is terrible because I had all 4 stars for every mission and was 2 stars away from all 4 on the combat simulators as well. I assumed maybe if I replace the battery inside this would fix the problem, but the cartridge can't be opened without a special tool for those star-headed screws that keep is closed. Is there any way to keep all those beaten missions and simulators? If not forget about it, its time I move onto another game.
