Thanks to PCBway for sponsoring this video! We recently received a Toploader NES that was destroyed by a failed mod attempt. Instead of giving up and throwing it in the trash, we used Redherring32's new Opentendo Toploader project to resurrect this console with a brand new open source NES motherboard! This project opens up all sorts of interesting possibilities, including the ability to convert a Frontloader NES into a Toploader!

Check out for more video game console repairs and mods!


Bill of Materials:

Parts that can be sourced from an NES (Frontloader or Toploader):
