A modded keychain-sized Nintendo Wii “Kawaii” runs full GameCube games without emulation

Popular modder and retro console enthusiast Tito from Macho Nacho Productions recently tested a Nintendo Wii the size of a literal keychain. He put the mini Wii console, known as the Kawaii, through its paces in a hands-on video, and it’s capable of running GameCube games without any gimmicks or shortcuts like emulation or Raspberry Pi boards. It’s simply a heavily trimmed-down motherboard, meticulously fitted inside a CNC-machined aluminum shell that serves as a heatsink.

In his video, Tito gave a brief introduction to the Kawaii and shared his excitement, stating, “This might be the smallest Nintendo GameCube ever made, and it’s running real Nintendo hardware. The Kawaii takes an actual Wii motherboard and somehow shrinks it down into a keychain-sized, fully functional system. No emulation or shortcuts.”

An ambitious mini-maximalist project

The minds behind this ingenious Nintendo Wii mod are YveltalGriffin and WeskMods. Both modders challenged themselves to create the smallest possible Wii known to humankind, and they’re thrilled with how it has turned out.

Earlier, YveltalGriffin stated on BitBuilt Forums, “The ninjas can’t stop this portablizer. I received the anodized aluminum prototype shells from @Ding earlier this month. In person, they actually look better than the renders.”

After all the blood, sweat, and tears poured into the project, the modders managed to shrink the Nintendo Wii into a 60 x 60 x 16 mm piece of hardware with a beautiful blue anodized aluminum unibody finish, complete with laser-etched artwork and a few acrylic windows that give off RGB hues. To top it all off, it also comes with a keychain loop.

Under the hood, the Kawaii uses an undervolted Omega-trim Wii motherboard with Thundervolt hardware and a breakout PCB for SD card or USB support. Furthermore, a 12-pin magnetic pogo-pin connector, like MagSafe for retro hardware, sends power, handles video, and even carries controller signals.

An add-on dock for wired controller support

Additionally, an add-on dock allows players to use four full-size GameCube controller ports along with composite and component video output and stereo audio. The whole package is passively cooled; still, it runs fairly hot while playing games like Mario Kart: Double Dash and Crazy Taxi. However, the games themselves run smoothly on the trimmed Wii hardware.

Tito used an external fan to blow on the Kawaii while running it for more than half an hour; otherwise, it would shut down after about 20 minutes as a safety precaution.

The modders behind the Kawaii project have made it clear that this isn’t for the faint of heart. YveltalGriffin stated, “Kawaii will be a challenging build, and there won’t be a full kit you can buy or even a step-by-step assembly guide.”
