New Family Computer controller repair button rubber. All silicone rubber buttons of the Famicom controller can be replaced. Includes diagonal input improvement stickers. Also compatible with the Sharp Twin Famicom console controller, 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). This is a compatible part and not a genuine part. Due to slight size differences in compatible parts, the cross key may be difficult to input diagonally. In that case, applying the included sticker to the back of the key will improve it, so please use it as needed when replacing the cross rubber. When applying, stick it exactly where the convex part of the rubber touches. If it is misaligned, it will not operate correctly. A separate precision Phillips head screwdriver (+ No. 1) is required to replace the buttons. These are parts for you to repair yourself. I don't think there will be any difficult work, but as it is a repair of a retro game console, we cannot provide any support. Please understand. We will ship via trackable anonymous delivery. * Please ask any questions before purchasing to prevent trouble. No greetings or other messages are necessary after purchase. I will basically not use the "message section after purchase," so please wait for the product to arrive after the payment process. Thank you.
