Many years ago, Nintendo indicated that Wii U would eventually get support for GameCube games on Virtual Console, but the system is quickly approaching the end of its life and they are nowhere to be seen. However, if the latest report from Eurogamer is to be believed, that feature will be available on Nintendo's next console, the Switch.
According to three separate Eurogamer sources, Nintendo plans to bring GameCube games to the Nintendo Switch Virtual Console, and they currently have three titles up and running. Those games are Super Mario Sunshine, Luigi's Mansion, and Super Smash Bros. Melee. A fourth game, the GameCube version of Animal Crossing, is reportedly being tested for release as well. If Nintendo successfully gets it running on Switch, it will apparently include all of the classic NES games that you can obtain and play in the game on GameCube.
The Nintendo Switch Virtual Console is reportedly being developed by Nintendo European Research and Development (NERD), which is the team that designed the NES Classic Edition plug and play console. Nintendo is also apparently looking into support for the Wii U's GameCube controller adapter, but a final decision has not yet been made.
Eurogamer has reached out to Nintendo for comment on this story, but Nintendo declined. Insiders Liam Robertson and Emily Rogers are both corroborating this story, as is reliable Switch leaker Laura Kate Dale.
