This is a portable Wii I built that uses original Wii hardware, so that everything runs at full speed and there's no emulation.
The Wii was homebrewed with a program called Portablizemii, which is designed for making handhelds like this.
I named this portable The Louii after Louie from the Pikmin series.
The system gets 5 hours and 15 minutes of battery life when playing GameCube games. Let me know if you have any questions for me!
