If you're a Nintendo fan with a soft spot for the GameCube era, recent developments might have just lit up your nostalgia meter. New filings from Nintendo submitted to the FCC suggest the possibility of a new GameCube-style controller potentially designed for playing classic titles via the Nintendo Switch Online service—possibly on the upcoming Switch 2.

As first highlighted by Nintendo Life, the Japanese gaming giant has filed paperwork for a "game controller" that aligns with the rumored features of the next-gen Switch console. The filing hints at a wireless Bluetooth-enabled device, sparking speculation about its design and intended use.

The rumor mill really kicked into high gear when Famiboards dug into the documents and noticed an image showing a label placement that eerily matches the back of a traditional GameCube controller—specifically where the label appears behind the C-Stick.

After all, the current Nintendo Switch Online service already supports classic controllers for NES, SNES, N64, Sega Genesis, and Game Boy titles.

This revelation has fans buzzing with anticipation over the potential arrival of a full GameCube game library coming to Switch Online—especially now that Switch 2 compatibility has been confirmed. For years, players have been calling for access to iconic GameCube titles, so this may finally be the year Nintendo answers the call.

What We Know About the Nintendo Switch 2 So Far

The Switch 2 made its debut in a short teaser trailer released in January, giving fans their first official glimpse. Among the confirmed features were backwards compatibility capabilities and the inclusion of a second USB-C port. However, several mysteries remain unsolved—including the function of a newly introduced Joy-Con button and the popular theory that it might support mouse-like input functionality.

Adding to the intrigue, a recent Nintendo patent revealed the potential for Joy-Con controllers to be attached upside down. Unlike the original Switch, which used locking rails to secure Joy-Cons in place, the next iteration is believed to rely on magnets—allowing them to attach on either side.

While this change might seem minor from a hardware perspective, it opens up customization options for users, such as choosing where buttons or the headphone jack are positioned. If implemented in the final version, this flip-friendly design could even lead to innovative gameplay mechanics.

Could Classic GameCube Games Come to Switch Online?

With rumors swirling around a potential GameCube controller integration, it's natural to speculate that Nintendo is preparing to bring a curated selection of GameCube classics to its subscription service. This would mark a major milestone for Switch Online, which has previously focused on earlier generations of Nintendo titles.

Analysts predict the Switch 2 will likely retail between $400 and $500, with a possible June release date. While we await official confirmation, Nintendo has scheduled a Direct presentation for April 2nd, where more details about the console—and perhaps its nostalgic offerings—are expected to be unveiled.

Until then, Metroid Prime Remastered remains a fantastic way to relive some of that legendary GameCube magic on your current Nintendo Switch.
