This is an AC adapter for the SHARP Twin Famicom AN-505. It used to work, but I don't have the console anymore, so I haven't been able to confirm its operation for this listing. If it doesn't work, I'm willing to accept a return, with the buyer paying the return shipping cost of 500 yen. The cable was bundled with it, so I'm including it as a bonus. If the cable doesn't work, I apologize, but it's a bonus and not eligible for return. It will be shipped via anonymous Yu-Packet Plus delivery.
