How to fix a Super Nintendo 

The screws are called either Torx if it's star shaped or Allen if it's 6 straight sides. It's one of the most common faults on the old cartridge based consoles, dirty pins on the console or the game, nice work saving it from the dump.

Nice job resurrecting the classic retro console good sir.🕹🙌🎮☘️

That's all it was, just dirty pins? Easy fix! 😺 Congrats.

Did u take that cart out without the eject button, you heretic? 🤣 Jokes aside, good work keeping another SNES on the go! 👍
