This is an adapter that allows you to use various USB controllers with a real GameCube console. It is a handmade product. It was created based on joypad-os. You can find more details by searching for "joypad-os git". The profile is set to default. Connection method: When you connect it for the first time, the LED will blink. Connect your controller or dongle via USB-C as shown in the example image. Once the LED stops blinking, it is ready to use. Controllers tested: ・PS5 controller (wired) 　Works normally. ・xbox360 wired controller 　Recognized, but the operation is unstable. ・Switch controllers (wired) 　Recognized, but the L and R buttons do not work, so it is not recommended. ・8BitDo Pro 2 Bluetooth Gamepad (wireless, tested with dongle) 　Works normally. ・8BitDo Arcade Stick (wireless, tested with dongle) 　Works normally. It should recognize any X input controller. There are multiple units in stock, so please let me know if you want more than one. The price on this page is for one unit. The case itself is 3D printed, so there may be scratches or dents (there are individual differences). Thank you for viewing.
