Wow it working thanks for assisting me. I used vinegar to clean my camera so it working now
Thumb down! Step 5 says, “All cleaned up!” But the picture shows much corrosion still present. Asking for further problems! Look up: "Nintendo Gameboy Pocket Shell-Side Battery Terminal CorrosionRemoval” for tips how to do it more thoroughly.
