This screwdriver set is perfect for anyone who wants to repair or modify their retro game consoles and cartridges. Whether you're a gamer looking to fix a beloved console or a DIY enthusiast, this set has you covered. The set includes 3.8mm and 4.5mm screwdrivers with an ergonomic grip for easy handling. The Gamebit shaft length is 7.5cm, and the total screwdriver length is 15.5cm, making it suitable for accessing deep screw holes in consoles like the GameCube and Virtual Boy. Compatible with popular consoles such as NES, SNES, N64, GameCube, Game Boy, Master System, Megadrive, and more, as well as various cartridges. Use it to open consoles and cartridges for tasks like cleaning, replacing batteries, and recapping motherboards. Note that opening your device may void the warranty (which probably expired long ago anyway).
