Playing Mario Kart 64 online with your friends used to mean accepting one hard truth: lag was part of the deal. That changes now.
Nintendo has confirmed that the full Nintendo 64 library available through Nintendo Switch Online + Expansion Pack now supports online play with up to four players, with enhanced features specifically for Nintendo Switch 2 members. The upgrade brings rollback-style netcode improvements to classic N64 titles, meaning the input delay and rubber-band lag that plagued earlier online sessions should be significantly reduced.

What the N64 library looked like before this
For years, the Nintendo Switch Online + Expansion Pack tier offered N64 games with basic online functionality. You could technically play with friends remotely, but the experience was inconsistent. Peer-to-peer connections meant that whoever had the worst internet connection dragged everyone else down. For fast-paced games like F-Zero X or GoldenEye 007, that was a real problem.
The original implementation also lacked the kind of input prediction that modern fighting game fans take for granted. Rollback netcode, the gold standard for competitive online play since games like Guilty Gear Strive popularized it, essentially predicts player inputs and corrects mistakes invisibly rather than freezing the game to wait for data packets. The absence of that technology made N64 online feel like an afterthought.
The upgrade and what it actually means
Nintendo isn't just patching a handful of popular titles. The enhanced features now apply across the entire N64 library for Switch 2 players. That means everything from Banjo-Kazooie to The Legend of Zelda: Majora's Mask gets the upgrade.
Up to four players can connect online, which lines up with the original N64's four-controller port design. For games that were built around four-player chaos, like Mario Party or Mario Kart 64, that number matters.
This repositions retro gaming on the platform. Nintendo has historically treated its classic game libraries as a passive archive, something you browse occasionally for nostalgia. Bringing proper online infrastructure to the N64 catalog turns those games into active multiplayer options again.

What most players miss about this announcement
The N64 upgrade is part of a broader expansion of what Nintendo Switch Online + Expansion Pack delivers on Switch 2. The same membership tier now also unlocks a library of classic Nintendo GameCube games, which is its own significant addition. Expansion Pack members additionally get upgrade packs for The Legend of Zelda: Breath of the Wild and The Legend of Zelda: Tears of the Kingdom on Switch 2, plus the N64, Game Boy Advance, and SEGA Genesis libraries.
That stacks up to a meaningful value proposition for anyone who already owns a Switch 2 and pays for the higher membership tier. The monthly cost hasn't changed, so existing subscribers get the N64 online improvements without paying anything extra.

The competitive angle worth watching
Retro gaming communities have spent years building their own rollback solutions for N64 titles through emulation projects like Mupen64Plus and various netplay plugins. Nintendo addressing this gap officially matters to a segment of players who previously had no reason to use the official service for online N64 play.
Whether the official implementation matches what dedicated emulation communities have achieved is a fair question. The proof will come from players testing latency across different connection types over the next few weeks. Early impressions from the Switch 2 launch period have generally been positive about Nintendo's online infrastructure improvements, but N64 netcode quality will need real-world testing at scale.
