My edition of the portable wii
I built a portable Wii with all the original I/O, including the GameCube ports and IR sensor. It has a built-in screen (capable of a maximum resolution of 1080p, although the Wii itself doesn’t support that resolution).
For power, it uses six 18650 batteries, providing around four hours of playtime. To make room for the batteries, I had to remove the DVD drive, but games can still be played through the USB port using USB Loader GX. I also added a battery charge meter and a switch because the wii consumes power when idle.
