This controller is exclusively for Super Smash Bros. Ultimate. I previously purchased a custom GameCube controller and customized the stick and buttons. (The code and buttons are unified in blue.) I haven't used it much, and I'm selling it now because I stopped playing Smash Ultimate. Features: ① Clicky Z button ② L/R button modification ③ Anti-snapback measures ④ Vibration motor removed ⑤ Paracord cable ⑥ Left/C stick (Rippie Stick) ⑦ ABXY buttons (e-room buttons) I have confirmed its operation, but I will re-check it before shipping. I guarantee the operation of this product with Super Smash Bros. Ultimate, but I do not guarantee its operation with other devices or games. Thank you for your understanding.
