  1. For anyone interested in this adaptor, please make sure you have the ability and suitable equipment to solder parts of the product to the right position.
  2. You have to source the CPU and PPU chips on your own. We will pack the IC sockets with the mainboard but they will not be soldered on the PCBA.
  3. You have to source the OG reset switch on your own or just use Cherry MX switch instead. The 3D print small part for Cherry MX switch would be included in the parcel. ( Check the post for more information: https://twitter.com/RgRDev/status/1621048799279079432 and https://twitter.com/RgRDev/status/1617572119180873728, or you can print your own using the STL file we uploaded: https://www.thingiverse.com/thing:6207935 ). Unfortunately there is no way for us to source any brand new reset switch which is the same as the OG one in the market.
  4. You have to source the 1P 2P gamepad port plug on your own, or you can simply solder the wires of gamepad to the mainbaord directly. (Unfortunately, there is no way for us to source any brand new port plug that is the same as the OG one in the market.)

Optional parts:

Famicom Power Adapter Board

A must-have optional part from us is the Famicom Power Adapter Board, ( for full description, please check this page: https://retrogamerestore.com/store/famipoweradapter/ )

Famicom Compoisite Adapter

It is to get the best quality of composite video from your Famicom console as the curcit path is super short and it would get rid of most noises from mainboard itself. You can place this adapter under the PPU of Famicom, just remove the 2SA-937 from OG Famicom Board, and solder three pins (Video, VCC, GND) and one wire from video output point. That’s all.
