Nintendo Switch Online’s MAR10 Day Update: Mario Classics Arrive as Virtual Boy and GameCube Libraries Grow

What’s new: Three Mario classics hit Nintendo Switch Online on March 10

Nintendo is marking MAR10 Day with a trio of retro additions to Nintendo Switch Online (NSO) + Expansion Pack on Monday, March 10, 2026: Mario’s Tennis (1995) and Mario Clash (1995) join the Virtual Boy app, while Mario vs. Donkey Kong (2004) lands in the Game Boy Advance app. All three require the Expansion Pack tier and are available on both Switch and Switch 2 where applicable.

Why it matters: these drops extend Nintendo’s newer “Nintendo Classics” push into platforms beyond the original NSO launch set, and they arrive amid an ongoing rollout of Virtual Boy and GameCube support tied to the Expansion Pack (with GameCube available on Switch 2). (nintendo.com )

The state of Nintendo Switch Online in March 2026

NSO now spans eight classic libraries across two membership tiers. At a glance as of March 2026:

• NES: 81 games
• Super NES: 77 games
• Game Boy / Game Boy Color: 43 games
• Nintendo 64: 42 games (plus a Mature-rated N64 app)
• Sega Genesis / Mega Drive: 50 games
• Game Boy Advance: 27 games
• Virtual Boy: launched with seven titles and more incoming
• GameCube (Switch 2 only): eight games live, more announced

These counts and categorizations are tracked by Nintendo Life’s continually updated NSO guide, and Nintendo’s regional pages confirm both the N64 Mature app and the Switch 2–only GameCube library within the Expansion Pack. (nintendolife.com )

Virtual Boy on NSO: what you need to know

Nintendo launched the Virtual Boy – Nintendo Classics app on February 17, 2026 for Expansion Pack members. A dedicated accessory is required to play, and Nintendo notes the accessory is available to purchase separately for NSO members. The MAR10 Day additions of Mario’s Tennis and Mario Clash expand the day-one lineup. (nintendo.com )

• Platform access: NSO + Expansion Pack
• Hardware: Switch or Switch 2 with Virtual Boy accessory
• Availability: global roll-out; check your regional eShop listing

GameCube classics arrive for Switch 2

With an Expansion Pack membership on Switch 2, players can access a growing library of GameCube titles via the Nintendo GameCube – Nintendo Classics app. Nintendo name-checks The Legend of Zelda: The Wind Waker and F‑ZERO GX among the headline offerings, with more titles planned. (nintendo.com )

Nintendo-focused outlets also continue to flag forthcoming GameCube additions; for example, Super Mario Sunshine has been acknowledged for the app but is still awaiting a formal date. (nintendoeverything.com )

Today’s drop: details on the MAR10 Day trio

• Mario’s Tennis (Virtual Boy, 1995): A foundational Mario sports entry adapted to the Virtual Boy’s stereoscopic display, now playable via the Virtual Boy app with Expansion Pack. (nintendolife.com )
• Mario Clash (Virtual Boy, 1995): A 3D twist on classic Mario Bros. arcade action, also joining the Virtual Boy app. (nintendolife.com )
• Mario vs. Donkey Kong (GBA, 2004): The puzzle‑platformer that spun out of Donkey Kong ’94 arrives in the GBA app for Expansion Pack members. (nintendolife.com )

Nintendo, GameSpot, and other outlets have promoted the March 10 timing to align with MAR10 Day celebrations. (nintendoeverything.com )

Membership tiers, pricing, and perks (U.S.)

• Nintendo Switch Online (standard): $19.99 per year individual; $34.99 per year family (up to 8 accounts). Includes online play, cloud saves (in supported titles), and access to NES, SNES, and Game Boy libraries. (nintendo.com )
• Nintendo Switch Online + Expansion Pack: $49.99 per year individual; $79.99 per year family. Adds Nintendo 64, Game Boy Advance, Sega Genesis/Mega Drive, Virtual Boy, and (on Switch 2) GameCube Classic libraries, along with select first‑party DLC. (en-americas-support.nintendo.com )

Nintendo is also running a free access period for GameChat on Switch 2 through March 31, 2026; after that date, a paid NSO membership is required. (nintendo.com )

How to find and play the new NSO games

• Update your console software and NSO apps from the eShop.
• Download “Nintendo Classics” apps for each system library tied to your tier (e.g., Virtual Boy, Game Boy Advance, GameCube on Switch 2).
• Launch the relevant app, scroll to the newly added titles, and start playing. Save states, suspend, and (for some systems) rewind remain supported, and many titles include online or local wireless play. (nintendolife.com )

Tip: If you’re on Switch 2 and plan to use GameChat, connect a compatible USB‑C camera and confirm parental controls if your family settings apply. The feature remains free to use until March 31, 2026. (nintendo.com )

The bigger picture: cadence and curation

The MAR10 Day trio underscores Nintendo’s recent cadence of small but steady monthly drops while it scales newer platforms like Virtual Boy and GameCube inside the Expansion Pack. Nintendo’s official pages frame these as “growing libraries,” and independent trackers show a healthy ramp since late 2025 across N64 (including a Mature‑rated app), GBA, and now Virtual Boy and GameCube. (nintendo.com )

Expect more first‑party favorites and a sprinkling of third‑party surprises over the next few months. Nintendo and enthusiast outlets have already teased unannounced or undated additions, including further GameCube titles following the initial set. (nintendo.com )

Bottom line

On March 10, 2026, NSO + Expansion Pack expands again with three Mario classics across Virtual Boy and GBA, advancing Nintendo’s multi‑platform retro strategy just as GameCube and Virtual Boy era content come into focus. If you’ve been waiting to revisit these slices of Mario history—or to explore the wider “Nintendo Classics” catalog—this is the best moment yet to check your membership tier, update your apps, and dive in.
