Replacement silicone rubber buttons for the Famicom controller. Includes diagonal input improvement stickers. Compatible with controllers for the Sharp Twin Famicom, Hudson Joycard mkII, and Hori Commander. ※ The square B and A buttons of the original Famicom cannot be replaced. ※ Not compatible with the New Famicom (gray Famicom). ※ Not compatible with the Nintendo Classic Mini Family Computer (mini Famicom that cannot use game cartridges). These are compatible parts and not genuine parts. These are new button rubbers for repairing Famicom controllers. Due to slight size differences in compatible parts, the cross key may be difficult to input diagonally. In that case, applying the included stickers to the back of the key will improve it, so please use them as needed when replacing the cross rubber. When applying, stick the sticker exactly where the raised part of the rubber touches. Misalignment will prevent correct operation. A separate precision Phillips head screwdriver (+No.1) is required for button replacement. These are parts for self-repair. While the work is not difficult, this is a repair of a retro game console, so we cannot provide any support. Please understand. Shipped via trackable anonymous delivery. ※ Please ask any questions before purchasing to prevent problems. After purchase, messages such as greetings are not necessary. I 'basically do not use the message section after purchase', so please wait for the product to arrive after the payment process. Thank you.
