DS/3DS/Wii/Wii U to Switch 2 Online in 2026?

Nintendo Switch Online has grown into the best home for retro Nintendo games—and with Switch 2 bringing GameCube to the service (and a surprise Virtual Boy revival with a replica headset), it raises the big question: what would it take to add DS, 3DS, Wii, and Wii U to NSO? In this video, I break down—practically and realistically—how each missing system could work on Nintendo Switch Online, what control and hardware workarounds Nintendo would need, and why early 2026 feels like the right window to roll it out without overwhelming the current lineup. What’s inside: Nintendo DS on NSO: Proven viability (Wii U VC layouts), vertical modes, dual-screen customization, and simple substitutes for mic/blow mechanics (voice or mapped inputs). Nintendo 3DS on NSO: Same dual-screen solutions plus the big one—bringing back lost eShop classics (Pushmo, BoxBoy, Rusty’s Real Deal Baseball). Why 3D isn’t a dealbreaker and how optional accessories (like glasses) could be a novelty, not a requirement. Wii on NSO: Motion controls without a sensor bar, Joy-Con mapping challenges, and why it’s still feasible (and valuable) even if it requires extra engineering to feel right. Wii U on NSO: The toughest nut to crack. Options like using a second Switch as a GamePad or selling a standalone GamePad-style accessory (~$150 range) so asymmetrical gameplay and touch-screen features actually work. Why titles like Wind Waker HD and Twilight Princess HD matter here, alongside niche picks like Color Splash. Why this is likely: GameCube’s arrival on Switch 2, Virtual Boy’s shock announcement, Nintendo’s tiered NSO strategy, and the easy win of selling more official controllers/accessories (vertical grip for DS, Wii Remote-style controller, a modern GamePad, etc.). Bonus thought: More non-Nintendo systems on NSO? Genesis is already here—Atari feels plausible; Xbox is a stretch but not unthinkable given recent moves. For players who grew up on DS, 3DS, Wii, and Wii U, centralizing everything on one device (especially Switch 2) isn’t just nostalgic—it’s convenience, preservation, and value. Imagine upgrading to the higher NSO tier because your entire childhood library becomes portable again. What would you want first—DS/3DS eShop revivals, Wii motion classics, or a Wii U solution?
