In the last episode we refurbished a corroded “Zelda – The Ocarina of Time” cartridge for the Nintendo 64. After this the cartridge worked fine, however I was not happy with how broken the gold edge fingers on the cartridge looked. So I looked around and wondered: maybe someone designed a replacement PCB for old cartridges? And sure enough: The N64 Preservation Project has PCB designs for the four major cartridge types. So I ordered some PCBs and we can rebuild the cartridge from the ground up!
