I have a very old SNES and a Donkey Kong Country 3 game. The last few times I played it, it seemed to randomly lose save games. People told me it was battery. Fine, I study electronics, I can fix that.
So I put in a battery holder and a new battery; all secured nice and tight. I played it for a few nights with no problems.
This morning, I took my SNES downstairs with the game in it. I plugged it in, and woop, the save game was gone.
Does anyone have any clue why this game keeps losing its save game?
I am not able to replicate this on purpose by doing the following:
- Wiggle the console while the game is in it. (like I would walk with it.)
- Shake the cartridge heavily in all directions (to make sure it is not the battery being faulty or disconnecting.)
- Plug in the power after no power for at least a few minutes.
Any advice is appreciated.
