GameCube Internal Bluetooth Kit (v3.5)

The GameCube Internal Bluetooth Kit is a modification that adds Bluetooth controller support directly inside a Nintendo GameCube console. Produced by LaserBear and designed by Greg, it allows up to four wireless controllers to connect simultaneously while keeping the original wired controller ports fully functional. The kit also enables remote power on and off of the console over Bluetooth.

Version 3.5 is the latest revision of the kit, introduced in 2026 as a restock. It is based on Darthcloud's open-source BlueRetro platform, which is known for achieving some of the lowest Bluetooth latency numbers when paired with a fast controller. Installation requires opening the console and performing some soldering, but the process is described as minimal.

The kit is sold through LaserBear's store for approximately $100 USD. It offers a clean aesthetic solution for players who want wireless controllers without external dongles, and the ability to connect multiple devices can make it a cost-effective option compared to buying several standalone adapters. However, those who only need a single controller or want to use Bluetooth across multiple GameCube systems are likely better served by a plug-and-play external adapter.
