Repair or modify your own games consoles and cartridges with the ZedLabz Game bit security screwdriver set.

In order to allow you to make your own console repairs and change your own batteries, you need to remove the casing tamper resistant screws using either a 3.8 or 4.5mm security screwdriver from this set.

Once the casing is opened you can complete various maintenance and repair tasks such as cleaning, replacing batteries, recapping motherboards and more.

The screwdrivers feature ergonomic full size handles and a long shaft length for the deepest screw holes, ideal for games consoles such as GameCube and Virtual Boy.

Please note that opening your device will in most cases void your warranty (which most likely expired long ago for most devices).

Additional information:

The technical name for Gamebit security screwdrivers is line head, this type of Japanese screw became synonymous with gaming, hence the nickname Gamebit was born to describe this type of security fastener screw which was commonly used by in older games consoles.

These are sometimes called as reverse torx / hexalobe, they are similar in style with the primary difference being that torx drivers are male whereas game bit drivers are female, and so the reverse of torx.

They fall under the broader banner of tamper resistant screws or security screws and were used to deter people from opening devices for various reasons, such as to stop you from repairing the device yourself, or to protect the technology inside and try to prevent piracy.

The sizing commonly associated with gamebit, 3.8mm and 4.5mm are technically wrong but widely associated and accepted to describe size of tool required to remove the security screws from retro devices, the correct sizes are actually 3.6mm and 4.6mm from a technical specification standpoint.

One of the most popular uses of these tools is to access and replace CR2016, CR2025 and CR2032 coin batteries in old game cartridges.
