Fan Discovers GameCube Dev Kit In Early Wii Menu Build

A GameCube development kit has been found in an early build of the Wii’s menu. Shared by Forest of Illusion and provided to them by an anonymous community member, it’s possible that this was discovered on the very first Wii menu — the one used during E3 2006.

Our friends over at Time Extension reached out to Forest of Illusion for more details on this discovery, which is apparently the TDEV dev kit. And, according to the Nintendo preservation site, there’s a chance this was the model that showcased a number of games at E3 2006, the year the Wii came out, including Zelda: Twilight Princess — which launched on both the GameCube and the Wii.

The original version 0.1 Wii menu was discovered after the huge Nintendo leak back in 2020, but with so much information, avid Nintendo fans have been digging through the details ever since. Among the other games demoed on the TDEV kit were Wii Sports, WarioWare Smooth Moves, and Excite Truck.

Forest of Illusion also shared with Time Extension a forum post from way back in 2006, with the user Teddman saying that “no one at E3 played the Wii version of Zelda–it was all the GameCube version rigged up to the Wii controller.”

We’re sure there’s still so much more to come out of this gigaleak, including even more snippets of info from this dev kit. Maybe we’ll see those game demos out in the wild someday!

We want to thank Forest of Illusion and the community for their continued work in preserving Nintendo’s history, and Time Extension for bringing this to our attention! Go have a read of the full article for more information.
