So, I basically had a Pokemon Emerald cartridge, I was using a CR 2025 battery, I originally did this with Pokemon Ruby and had no problems, I had my Pokemon Emerald cartridge's battery dead, so I replaced it, on the first attempt, I didn't screw in the screw and booted the game, it worked but reported the battery ran dry, so I took it apart yet again, got some copper wiring, and noticed that the circuit wasn't properly connecting, so I stripped the insulation off, coiled it up, and put it in between the loose connectors, then closed it without screwing it in, and then inserted it into the Gameboy Advance SP, it fit well into the slot, but the Gameboy wouldn't turn on, so I removed the cartridge and it powered on fine, I turned it off and inserted the cartridge yet again and it still didn't turn on... how do I fix this?
