Nintendo Switch Online’s “Expansion Pack” is the higher‑tier paid membership that adds extra classic game libraries and some bonus DLC on top of the standard Nintendo Switch Online service.

What the Expansion Pack Is

In simple terms, Nintendo Switch Online + Expansion Pack is a subscription tier that includes:

  • All regular Nintendo Switch Online benefits (online play, cloud saves, NES/SNES and basic classics apps).
  • Extra retro platforms and games, like Nintendo 64, Game Boy Advance, SEGA Genesis/Mega Drive, Virtual Boy, and more recent additions over time.
  • Access to certain game DLC “upgrade packs” at no extra cost while you stay subscribed.

Think of it as Nintendo’s “deluxe” online plan: you pay more per year but unlock a much bigger retro library plus some premium add‑ons.

Key Features Included

Here are the main things you get with Nintendo Switch Online + Expansion Pack:

  • Retro game libraries : Apps for Nintendo 64 and SEGA Mega Drive/Genesis were the original headline features. Over time, Nintendo expanded this to include Game Boy Advance and Virtual Boy (plus other systems, including GameCube on Switch 2).
  • Virtual Boy additions : As of 2026, Virtual Boy titles like Mario Tennis and Mario Clash are included for Expansion Pack subscribers, with more Virtual Boy games rolling out and even special accessories promoted for the 3D effect.
  • Select DLC included : Certain big‑title expansions are bundled:
    • Animal Crossing: New Horizons – Happy Home Paradise.
* Mario Kart 8 Deluxe – Booster Course Pass.

* Splatoon 2 – Octo Expansion.

These are available to you as long as you keep an active Expansion Pack membership.

Nintendo’s own marketing highlights that this tier “gets all the benefits of Nintendo Switch Online, plus access to classic Nintendo 64, Game Boy Advance, Virtual Boy, SEGA Genesis and other systems’ games, along with select upgrade packs and DLC.”

Short, Practical Take

If you just need the answer in one line:

  • The Expansion Pack is an upgraded Nintendo Switch Online subscription that adds extra classic consoles (like N64, GBA, Genesis, Virtual Boy, and more) and select DLC for games such as Animal Crossing: New Horizons, Mario Kart 8 Deluxe, and Splatoon 2, on top of the base online service.
