Chosen Solution
My gameboy turns on normaly. The nintendo logo flies down and makes the nostalgic DING sound. Then the splash screen of any game appears but after that the games just crash. With tetris you hear the first note of the title song then it skips back to the splash screen. With super mario land 1 the first screen appears. I press start then the music glitches out and the mario sprite never shows up. I can use the buttons but all the sprites are glitched and messed up. The games work fine in my super gameboy on the SNES so this has to be because of the gameboy not the games. I clead all the contacts in the gameboy and the games. Here’s a video with an example what happens. https://www.youtube.com/watch?v=pZ2hgeDJ… Update (09/24/2016) I tried the alcohol already. I cleaned out the games, I cleaned the gameboy pins multiple times…. Nothing worked. The same problem kept persisting. I’m not really that much of techie so I can’t really follow the pcb all that much. I took some photos but I don’t know if they are clear enough.
The only easy suggestion I can make is to clean the game pin contacts with some rubbing alcohol. One of the easier ways to do that is to pick a game, clean it with a good amount of alcohol, so it’s rather wet and insert it into the game slot, that’ll help clean out the contacts a bit. You could also squish the end of a cotton swab a bit to fit it in there and clean the contacts as well. If that doesn’t help, it’s time to open up the Gameboy and look over the PCBs. Luckily they aren’t hard to follow and you might be able to find some dodgy sections that are damaged in one form or another. Try out the rubbing alcohol first and see if that helps. It if doesn’t, open up the Gameboy and post some pics of the internals if you can’t find any spots that appear questionable. You’ll probably need a tri-wing driver to open it up as well.
