WEPUSEN Gamebit Security Tri-wing Y Trigram Screwdriver 3.8mm 4.5mm Nut Bits Screw Driver for Gamecube, NES SNES N64 Wii NDS, Gameboy Advance Sega Game Gear Tool Kit

Let me clean and repair my Gameboy from when I was a kid.

If you’re into tinkering with game cartridges, this is a great thing to pick up.

Perfect tool for opening and cleaning retro video games.

The tools work great! The 2 nut drivers, although they work fine, have a single flaw. They will not fit into a drill or removable bit screw driver. I was however able to still remove the screws from a Super Nintendo game using them by hand.

Used to open a game gear. Worked exactly as it should.

Inexpensive but perfectly fine set for disassembling / reassembling game systems and cartridges! The game bits use a standard 1/4" drive and fit snugly on every screw head I've used them on (no stripping yet). I repair game systems / games, and my 3.8mm disappeared - for the price I went ahead and purchased this set! Never hurts to have spares, and they work just as well as my previous bit which cost $7 by itself.

I bought these for my Gameboy advance sp and they don’t fit. Neither do the adapter pieces. I just have it put away now in case I might need it for some other device. Oh well.

I will start off by saying the philips screwdriver is absolutely worthless. That being said, the security bits worked awesome. To the people complaining that the bits fall out of your screwdriver, get a new screwdriver. I had zero issues with them falling out.
