PLEASE READ - 5/16/24:

GameCube extension cables are known to bend the pins on the controller connector. Similar products that cause this damage include the Raphnet GameCube to N64 adapter. Controllers will often times remain functional, but the pins become un-seated from the plastic which allows them to get pushed in further.

If you have previously used a controller with one of these extensions or products, the Pocket Adapter will bend the pins in your plug to an unusable state. We recommend swapping your cable if you have used any of these products with your controller.

This adapter allows you to use your original GameCube controller on your PC and Nintendo Switch for all types of gaming. Supports up to 4 controllers simultaneously. 

This is a kit which requires some assembly. You only need a Torx T6 Screwdriver to assemble this adapter.

USB-C to USB-A cable (required for operation) is not included. We have cables available here.

This adapter is also compatible with USB-C to USB-C type devices such as Android phones.


  • Tested with Phob 2.0 and up, ProGCC, GameCube controllers, Hitbox, Snackbox, Frame1
  • Use your GameCube controller on your PC or Nintendo Switch.
  • Play Emulators, Steam, and much more. 
  • Compatible with USB-A and USB-C host devices.

Great product, easy build, very portable

The adapter was easy to build and works wonderfully!

Destroyed my Orange spice controller pins.

Huge bummer, but in practice the item works very well. It seems that with older controllers it'll just completely ruin the pins. It just mashed mine rendering it unusable. Purchase at your own risk.

Thanks for your feedback! After some thorough research by our team, we found that this damage is limited to OEM controllers that have previously been used with *GameCube Extension Cable* type products and/or *GameCube RaphNet Adapter* type products. Both of these feature the same female plug, which was not properly toleranced for OEM controllers. After plugging in an OEM controller to either of these products one time, the pins become un-seated from the lower plastic guiderail inside the connector. This will leave the controller functional, but primes it to have its pins pushed in.

We have updated the product page to reflect this information and would like to work with you in resolving the issue. Please reach out to us at

Amazing Adapter

One of the best in market. Inputs feel amazing, you're in absolute control. The compact size makes it such as easy carry. It's a extremely competitive product, an easy decision to have one of your own.

Destroyed my gamecube controller

This product will push the pins of your gamecube controller port inside of the housing and destroy your controller. Do not purchase this terrible product.

Thanks for your review! Please reach out to us at so we may look into this issue with you further!

The GC Pocket Adapter+ is THE adapter

Wow! This thing is amazing, it works with no extra drivers, has consistent polling, and a wonderful community supporting it. It's way smaller than I thought it would be, which is great for travelling. Will definitely be recommending this adapter to everyone I know that plays online melee

The only thing I would say is that the ball bearings are a bit tricky to put into the adapter.
Here's a quick tip, put your bearings in first and then set your springs in afterwards, that way the bearings wont slip all around :D
