Want to play classic Sonic without hunting down an old Mega Drive? If you've got a Switch or Switch 2, the official route is already sitting in Nintendo Switch Online, and it comes with a couple of tools that take the sting out of those 16-bit difficulty spikes.
This guide sticks to that route, because it's the one Nintendo documents. No ROM downloads, no dodgy emulators.
Get set up
1. Get the right membership. The SEGA Genesis library isn't in the base Switch Online plan. Nintendo's store page says it comes with Nintendo Switch Online + Expansion Pack: "With a Nintendo Switch Online + Expansion Pack membership, access a collection of SEGA Genesis™ games and more!"
*Expected result:* the SEGA Genesis – Nintendo Classics app becomes available to download.
Nintendo's listing is for Switch, and for Switch 2 it says: "Supported – Game behavior is consistent with Nintendo Switch." So the same app works on both.
2. Find the Sonic games. Nintendo names Sonic The Hedgehog 2 and Sonic The Hedgehog Spinball in the Genesis collection, along with Dr. Robotnik's Mean Bean Machine if you fancy Eggman's puzzle spin-off. Nintendo Life's running list puts the whole Genesis library at 50 games.
A heads-up: the original Sonic the Hedgehog and Sonic 3 aren't among the titles listed on Nintendo's page or in Nintendo Life's list right now, so don't expect the full Mega Drive run. *Expected result:* Sonic 2 and Spinball are ready to play in the app.
Use the tools that make it easier
This is where the Switch versions beat the original cartridges.
- Rewind. Hold ZL + ZR to rewind. Nintendo's own example is perfect: "rewind to recover rings in Sonic the Hedgehog 2." Missed a jump into a bottomless pit? Roll it back. *Expected result:* you skip the walk back from a checkpoint.
- Save states. Nintendo describes creating a save state before a boss, so you can retry the fight without replaying the whole act. *Expected result:* a hard boss stops eating your evening.
- Pick-up-and-play saving. Nintendo says you can "play, save, and jump back into the action whenever you have a few minutes", handy for a game that originally had no save system.
- Online play. Nintendo lists online play for up to two players, with screen sharing for co-op or competitive play. Sonic 2's two-player mode is a natural fit.
- CRT filter. If you want that old-telly look, there's a CRT filter too.
One fairness note: rewind and save states are great for learning a game, but if you're chasing a clean run or a personal best, try one without them.
Optional: the proper pad. If the six-button feel matters to you, Nintendo sells a SEGA Genesis Control Pad, but it's optional. Nintendo says it's "not required to play" the collection. There are catches: you need a paid Switch Online membership to buy it, it's limited to four per Nintendo Account, and it only ships to the US and Canada. Australian players will have to make do with a Joy-Con or Pro Controller.
Limits and troubleshooting
- Membership required. Let the Expansion Pack lapse and you lose access to the library.
- Not every Sonic game. Check the in-app list before you plan a marathon.
- Rewind isn't an undo for everything. Use save states before risky moments rather than relying on rewind alone.
Start with Sonic 2, set a save state before Metropolis Zone, and enjoy the classic without the classic frustration.
