In this video I show you how to replace the battery on your gameboy cartridge. This skill applies to basically all older Cartridge-based games with a save feature. NES, SNES, Sega, Gameboy and SOME N64 carts use this same type of battery.

For this game, you need a CR2025 battery with tabs already in place. You can also use a CR2032, which is just a higher capacity battery. It's perfectly fine for use.
