Nintendo just gave an eight-year-old game its biggest upgrade yet. On September 2, 2026, the company confirmed that Mario Kart 8 Deluxe has received a free software update on Nintendo Switch 2 that lets up to eight players race in local split-screen on a single console, doubling the four-player cap that has defined the series since the Wii U era. The update, version 4.0.0, went live around September 1, according to patch notes cited by IGN and Vooks, and Nintendo’s own announcement frames it simply: a free update to the existing game, not a new paid edition or DLC pack.
For a launch title that has anchored Switch hardware sales since 2017, that’s a meaningful move. It arrives more than a year after Switch 2 hit shelves, and it lands in the same window as Mario Kart World, Nintendo’s newer, standalone racer built specifically for the new console. Instead of retiring the older game, Nintendo is pumping fresh capability into it, and the eight-player mode is the headline feature people are searching for right now.

What Changed in Mario Kart 8 Deluxe’s Version 4.0.0 Update
Patch notes for version 4.0.0, reported by IGN, Vooks, and Nintendo Life, describe several changes bundled into the same release in September 2026. The headline addition is support for five-to-eight players in local Multiplayer mode, up from the previous ceiling of two-to-four players. Nintendo also added support for the Nintendo Switch 2 display and high-resolution TVs, which the company says produces clearer visuals, along with shortened loading times before races and battles begin, a change Nintendo Life specifically confirmed in its own coverage of the patch notes. Players who own the Mario Kart 8 Deluxe Booster Course Pass also gained access to 96 races within VS Race rules, an enhancement layered on top of the split-screen change rather than a replacement for it.
None of this requires a new purchase. Outlets including Engadget and Kotaku describe the update as free to download for anyone who already owns Mario Kart 8 Deluxe and is playing it on a Switch 2 console. Nintendo’s own news post states plainly that “a free update to the Mario Kart 8 Deluxe game is available now,” according to IGN’s coverage of the announcement.
How Eight-Player Split-Screen Actually Works
The mechanics are straightforward but demanding on hardware. According to patch notes referenced by IGN and Nintendo Life, and confirmed in Nintendo’s own support documentation as of September 2026, up to seven original Nintendo Switch controllers can join a session, but at least one Joy-Con 2 or Nintendo Switch 2 Pro Controller must be connected alongside the built-in controls to unlock the full eight-player mode, bringing the total to eight simultaneous racers on one screen. Nintendo Life’s reporting on the same patch notes zeroes in on that lone-eighth-controller requirement specifically, while IGN describes the resulting layout as carving up “the usual four-player split one more time,” producing eight portrait-style windows arranged across the display rather than four larger quadrants.
That’s a genuinely unusual configuration for a racing game. Most console racers that support split-screen at all stop at four, because rendering four (or eight) simultaneous camera views, physics simulations, and AI opponents in real time is expensive. Getting eight viewports running on one machine, even at a reduced frame rate, is only realistic because Switch 2’s silicon has meaningfully more headroom than the original Switch it replaces. Players chasing the sharpest possible image for smaller sessions can also pair the update with a 4K 120Hz VRR display setup for docked play.
A Free Update, Not a New Switch 2 Edition
One point worth clearing up: this is not a repackaged “Mario Kart 8 Deluxe Switch 2 Edition” with its own price tag, the way some other publishers have shipped paid current-gen refreshes of older titles. Coverage from GameSpot and Kotaku both frame version 4.0.0 as an update applied directly to the existing game people already own, whether they bought it years ago on the original Switch or picked it up more recently. There is no separate SKU, no new box art, and no indication in any of the reporting that Nintendo charged anything extra for the Switch 2-specific improvements.
That distinction matters for the millions of players who already own the game. It also matters strategically: Nintendo is using free updates to make its back-catalog more valuable on newer hardware, rather than asking fans to repurchase a game they already paid for once.
The Technical Tradeoffs: 30 FPS and Portrait Windows
Eight-player split-screen doesn’t come free of compromise. Video analysis cited in the update coverage indicates the eight-way mode is capped at 30 frames per second, matching the frame rate Mario Kart 8 Deluxe has historically used for its standard four-player split-screen. In other words, Nintendo didn’t trade frame rate for player count so much as extend the existing 30fps split-screen tier to accommodate twice as many racers.
Single-player and smaller-player-count sessions benefit differently. Nintendo’s own support documentation, updated alongside version 4.0.0 in September 2026, specifies native 2160p resolution docked and 1080p in handheld mode, both running at a full 60 frames per second outside the eight-player split-screen tier, paired with the “enhanced visuals” and high-resolution TV support Nintendo mentions in its own patch notes. The takeaway: solo racers and small local groups get a sharper, smoother image whether docked at a TV or on the go, while the eight-player mode trades resolution and frame rate for sheer player count, splitting the screen into eight narrower, portrait-oriented windows that IGN describes as a “ludicrous split screen” layout.
Split-Screen Player Counts Across Mario Kart History
Four-player local split-screen has been the ceiling for the Mario Kart franchise for roughly two decades. IGN’s coverage of the new update explicitly frames the eight-player mode as taking “the usual four-player split one more time,” which confirms that four has been the standing limit through the Wii U-era Mario Kart 8 and its Nintendo Switch port, Mario Kart 8 Deluxe. The table below lays out how the series has handled local split-screen historically, based on the series’ well-documented four-player standard and the newly confirmed Switch 2 jump to eight.
| Game / Platform | Max Local Split-Screen Players | Typical Split-Screen Frame Rate |
|---|---|---|
| Mario Kart 8 (Wii U) | 4 players | 30 fps |
| Mario Kart 8 Deluxe (original Switch) | 4 players | 30 fps |
| Mario Kart 8 Deluxe (Switch 2, pre-4.0.0) | 4 players | 30 fps |
| Mario Kart 8 Deluxe v4.0.0 (Switch 2) | 8 players | 30 fps |
| Mario Kart World (Switch 2) | Not part of this update | Not disclosed in this update’s coverage |

Why Nintendo Is Still Investing in an Eight-Year-Old Game
Mario Kart 8 Deluxe first launched in 2017 on the original Switch, itself a port of the 2014 Wii U game. That makes it one of the oldest titles in Nintendo’s current lineup, and yet it remains one of the system’s most consistently played games years after release. Rather than let it fade as Mario Kart World takes over as the flagship racer, Nintendo appears to be treating the older game as a long-tail asset worth continued investment, especially for local multiplayer and couch co-op, an area where the newer title hasn’t necessarily displaced it.
Kotaku’s coverage frames this explicitly as “Mario Kart 8 Deluxe” finally receiving “its big Switch 2 upgrade” more than a year after the console shipped, language that suggests Nintendo waited until the Switch 2 install base was established before dedicating engineering resources to a platform-specific overhaul of an older title. That’s a deliberate sequencing choice, not an accident.
Mario Kart 8 Deluxe vs Mario Kart World: Nintendo’s Dual-Track Strategy
GameSpot’s reporting draws a direct line between the two games, noting that “even with Mario Kart World aiming to usurp its position, Nintendo isn’t done dropping new content into Mario Kart 8 yet.” That’s a notable admission about how Nintendo is managing its own internal competition. Mario Kart World is the newer, Switch 2-native entry in the franchise, and it includes features like CameraPlay for online play. Nintendo’s own version 4.0.0 patch notes confirm CameraPlay support was added directly to Mario Kart 8 Deluxe in September 2026, and Engadget’s coverage points out that the updated game now supports CameraPlay online, functioning “just like in Mario Kart World,” with that camera-enabled online play scoped to sessions of two to four players, which suggests Nintendo is bringing feature parity to the older game rather than walling those capabilities off for the newer release only.
The practical effect is that Nintendo now runs two actively supported Mario Kart games side by side on the same console, each with a distinct strength: Mario Kart World as the modern, feature-forward flagship, and Mario Kart 8 Deluxe as the mature, content-rich title with the deepest track roster and now the widest local multiplayer ceiling in series history. The CameraPlay parity also builds on the console’s existing GameChat and GameShare features, which already let Switch 2 owners share gameplay across devices.
How This Compares to Split-Screen Trends on Xbox and PlayStation
Local split-screen has been in a slow decline across the industry for years. Big-budget racers and shooters on Xbox Series X|S and PlayStation 5 have increasingly leaned on online-only multiplayer, and when split-screen does appear, it typically caps out at two to four players, largely because rendering multiple simultaneous camera views at competitive visual fidelity is costly on any hardware. Against that backdrop, an eight-player local mode on a single console reads as a genuinely uncommon move in 2026, and it’s one that plays to a strength Nintendo has cultivated for decades: couch multiplayer as a system-selling feature rather than an afterthought.
It’s worth noting that the specific reporting on this update doesn’t include direct statements from Microsoft or Sony, and there’s no indication either company is racing to match an eight-player local split-screen mode of their own. The broader context, though, is that Nintendo is doubling down on a multiplayer format the rest of the industry has largely deprioritized, which reinforces Switch 2’s positioning as the console built around sharing one screen in the same room.
Market Impact: What This Means for Switch 2 Adoption
Switch 2 has already sold tens of millions of units globally since launch, according to Nintendo’s own hardware disclosures, and Mario Kart 8 Deluxe has long been one of the platform’s most-owned pieces of software going back to its original Switch release. A free feature like eight-player split-screen doesn’t require a new purchase, so it won’t show up directly in software sales charts, though GameSpot reported that Nintendo moved an additional 2.39 million units in February 2026, a figure the outlet tied to continued demand for the game’s split-screen multiplayer appeal even before version 4.0.0 shipped. What it can do is strengthen the case for households upgrading to Switch 2 hardware, since the expanded mode and the 4K single-player boost are both gated behind owning the newer console rather than the original Switch.
That’s consistent with a pattern Nintendo has used before: pairing hardware upgrades with meaningful, free software improvements to the games people already own, rather than relying solely on new releases to justify a console purchase. For families and groups who prioritize local multiplayer, an eight-player Mario Kart session on one television is a tangible, easy-to-demonstrate reason to make the jump, particularly as Switch 2’s sales momentum against rival consoles continues to be a closely watched storyline.
Historical Context: Split-Screen Gaming’s Slow Decline and Revival
Split-screen gaming peaked in the GameCube and Xbox 360 era, when titles across genres routinely supported two-to-four-player local sessions as a default expectation. As online multiplayer infrastructure matured through the PS3 and Xbox One generations, many major publishers scaled back or removed split-screen entirely, citing the engineering cost of maintaining multiple rendering passes on hardware that was also being pushed toward higher resolutions and frame rates. Mario Kart, notably, never abandoned the format, keeping four-player split-screen as a constant across the Wii U and Switch eras even as competitors moved away from it.
The jump to eight players on Switch 2 extends that streak rather than reversing a prior cut, which is part of why the announcement landed as a surprise. Nintendo wasn’t restoring a feature it had removed; it was expanding a feature it never gave up on, at a scale no prior Mario Kart game has attempted.
Industry Reaction and What Outlets Are Saying
Coverage across gaming outlets has largely framed the update as an unexpected, welcome surprise rather than a leaked or long-rumored feature. IGN, Engadget, Kotaku, GameSpot, Vooks, Nintendo Life, and CNET all published pieces within a day of Nintendo’s announcement, with CNET’s own report independently confirming the jump from four to eight local players on Switch 2 in September 2026, and several outlets describing the move using words like “wild” and “surprise” given that Mario Kart 8 Deluxe is nearly a decade old at this point. None of the coverage reviewed for this piece includes direct commentary from independent market analysts or from Microsoft and Sony, so the reaction so far is best characterized as strong player and press interest rather than a documented shift in competitor strategy.
What is consistent across outlets is the framing of this as a deliberate long-tail strategy: keep a franchise anchor title relevant and technically current on new hardware, using free updates instead of a new release, while a separate, newer entry in the same franchise handles the job of showcasing what a ground-up Switch 2 game looks like.
What’s Next for Mario Kart 8 Deluxe and Switch 2
Nintendo hasn’t detailed a further roadmap beyond version 4.0.0 in the reporting available at publication, though the update fits a broader pattern the company has followed across its wider gaming ecosystem this year. The Booster Course Pass addition of 96 races suggests Nintendo is still actively adding content to the pass’s rule sets, which could mean more updates land for pass holders even without another headline feature like the split-screen expansion. For now, the eight-player mode, the 4K single-player boost, and the shorter load times represent the full scope of the confirmed Switch 2 update.
Predictions: Where This Goes From Here
- Expect Nintendo to apply the same playbook, a free Switch 2-specific patch rather than a paid remaster, to other high-install-base back-catalog titles that support local multiplayer, following the pattern set by Mario Kart 8 Deluxe’s version 4.0.0.
- Mario Kart 8 Deluxe’s eight-player mode is likely to become a recurring talking point in Switch 2 hardware demos and in-store displays, since it’s a feature that’s easy to show off with multiple controllers in a single room.
- Nintendo will likely keep both Mario Kart games, 8 Deluxe and World, in active simultaneous support for the foreseeable future rather than sunsetting the older title, given the free content it just shipped.
- Other publishers with older, split-screen-capable franchises may face renewed pressure to revisit local multiplayer modes if Nintendo’s eight-player experiment generates strong player engagement data.
- Further Booster Course Pass updates for Mario Kart 8 Deluxe are plausible in the coming months, following the pattern of the 96 races added alongside this update.
Frequently Asked Questions
Is the eight-player split-screen update for Mario Kart 8 Deluxe free?
Yes. Nintendo’s announcement and coverage from Engadget and Kotaku confirm this is a free software update, version 4.0.0, applied directly to the existing game. There is no new purchase or separate SKU involved.
Do I need a Nintendo Switch 2 to use eight-player split-screen?
Yes. The expanded split-screen mode is part of a Switch 2-focused update, and reporting on the patch notes ties the eight-player capability specifically to Switch 2 hardware rather than the original Switch.
How many controllers do I need for eight-player split-screen?
Up to seven additional controllers can connect alongside the console’s built-in controls to reach eight total racers, and as of the September 2026 patch notes reported by IGN, those seven can be original Nintendo Switch controllers as long as at least one Joy-Con 2 or Nintendo Switch 2 Pro Controller is also connected to activate the mode.
What frame rate does eight-player split-screen run at?
Video analysis cited in coverage of the update indicates the eight-player mode runs at 30 frames per second, the same rate the game’s split-screen modes have historically used.
Does this update change Mario Kart 8 Deluxe’s price?
No. Reporting does not indicate any new pricing tied to the Switch 2 update. It’s described consistently as a free patch to the existing game rather than a new edition with its own cost.
Is this different from Mario Kart World?
Yes. Mario Kart World is a separate, newer Mario Kart title built for Switch 2. This update applies to Mario Kart 8 Deluxe, the older game originally released in 2017. GameSpot’s coverage frames the two as running in parallel rather than one replacing the other.
What else is included in version 4.0.0 besides split-screen?
Nintendo’s patch notes, as reported by outlets covering the update, also list support for Switch 2’s display and high-resolution TVs, shortened loading times, and, for Booster Course Pass owners, 96 additional races within VS Race rules.
Where can I read Nintendo’s official announcement?
Nintendo published the update details through its official Nintendo Switch news channel, with additional patch-note detail corroborated by outlets including IGN, Vooks, Engadget, and Kotaku.
