Over the last few years we’ve seen several projects that convert Nintendo’s Wii into a handheld console by way of a “trimming”, wherein the system’s motherboard is literally cut down to a fraction of its original size. This is made possible due to the fact that the majority of the console’s critical components were physically arranged in a tight grouping on the PCB. While it might not be the smallest one we’ve ever seen, the Wii SPii by [StonedEdge] is certainly in the running for the most technically impressive.
It took [StonedEdge] the better part of a year to go from the first early 3D printed case concepts to the fully functional device, but we’d say it was certainly time well spent. The general look of the portable is strongly inspired by Nintendo’s own GameBoy Advance SP, albeit with additional buttons and control sticks. In terms of software, the system is not only able to run Wii and Gamecube game ISOs stored on its SD card, but also several decades worth of classic titles through the various console emulators available for the system.
The Wii SPii makes use of a particularly difficult variation of the Wii miniaturization concept known as the OMEGA trim, and is supported by a custom PCB that’s responsible for things like power management and audio output. As it was never designed to be particularly energy efficient, the trimmed Wii motherboard will deplete the system’s dual 18650 cells in about two and a half hours, but at least you’ll be able to get charged back up quickly thanks to USB-C ..
