Overview

  • A new Macho Nacho Productions video showcases the finished Kawaii keychain console running real GameCube games on a heavily trimmed Wii board.
  • The device measures 60 by 60 by 15.8 millimeters and relies on an Omega trim of the Wii motherboard with NAND Flex to relocate chips and a Thundervolt mod to lower CPU voltage.
  • A magnetic dock supplies power over USB-C, breaks out video through cables, and offers four full-size GameCube controller ports.
  • The CNC aluminum shell cools the system passively, yet the unit runs very warm and can shut down during longer sessions, so a small desk fan helps keep it stable.
  • Design files on GitHub include MCAD, ECAD, and a full parts list, with a BitBuilt thread for reference, though step-by-step build instructions are not yet published.
