YouTuber GingerOfOz has built a GameCube handheld, a mythical device that surfaced in 2005 as the 'GameCube Advance'. At first glance, GingerOfOz's creation resembles the original, which turned out to be a fake. However, the YouTuber has made a few design changes, outlined in the video embedded below.
Specifically, he used Nintendo DS-style analog sticks to allow the device to be closed, which would have been difficult to engineer using equivalents from the GameCube controller. Additionally, GingerOfOz designed a more functional hinge and did not include a disk drive. Moreover, GingerOfOz did not base his portable GameCube on the console from which it derives its name.
Instead, GingerOfOz relied on the Nintendo Wii, which can play digital copies of GameCube games. For reference, the Nintendo Wii has a smaller cooling system and motherboard than the GameCube, along with a more efficient chipset. Hence, it was a more sensible choice in a project that prioritised compactness.
Still, the YouTuber modified the Wii's software to show the original GameCube logo at boot. While the Nintendo Wii has a less power-hungry SoC than the GameCube, it chews through 4,000 mAh of batteries in an hour of gaming. Unfortunately, GingerOfOz does not plan to mass-produce his creation nor publish a guide on how to build it at home.
