How to Play Physical Switch Cartridges on Switch 2

You do not need to repurchase your physical games. The Switch 2 features a unified cartridge slot located on the top of the console.

1. Open the game card slot cover on your Switch 2.
2. Insert the original Switch game cartridge (label facing you).
3. The game icon will appear on the Home Menu.
4. Select the game. You may be prompted to download an update patch before playing.

How to Transfer Digital eShop Games and Save Data

Your digital purchases are tied to your Nintendo Account, not the hardware. When you boot up your Switch 2 for the first time, you will be asked to link your account.

Steps to Redownload Digital Games:

1. Boot up the Switch 2 and select Link Nintendo Account during the initial setup.
2. Open the Nintendo eShop from the Home Menu.
3. Select your User Icon in the top-right corner.
4. Navigate to Redownload in the left sidebar.
5. Select the cloud icon next to any game to reinstall it on your new console.

Do Digital DLCs Work with Physical Cartridges?

Yes. Any digital DLC or Expansion Pass you purchased (such as the Mario Kart 8 Deluxe Booster Course Pass or Super Smash Bros. Ultimate fighters) is intrinsically tied to your Nintendo Account. When you insert a physical Switch 1 cartridge into the Switch 2, the console will automatically recognize your linked account and apply your digital DLC to the physical media.

MicroSD Card Transfers (What You Need to Know)

If you have a massive library on a MicroSD card inside your original Switch, you cannot simply hot-swap the card into the Switch 2 to avoid redownloading games. As a security and file-system measure, the Switch 2 will prompt you to format the MicroSD card upon insertion. You will need to wipe the card and redownload your software from the eShop. Fortunately, your save data is stored on the console's internal memory, not the SD card.

Steps to Transfer Save Data:

If you have a Nintendo Switch Online subscription, your save data is automatically backed up to the cloud. Simply download your game, press + on the game icon, and select Save Data Cloud -> Download Save Data.

If you do not have NSO, place both consoles next to each other. On the old Switch, go to System Settings -> Data Management -> Transfer Your Save Data -> Send Save Data to Another Console. On the Switch 2, select Receive Save Data.

Controller, Accessory, and Amiibo Compatibility

Players with large collections of peripherals will be happy to know that the Switch 2 ecosystem is highly accommodating. Your existing Joy-Cons and Nintendo Switch Pro Controllers can connect wirelessly to the Switch 2 via Bluetooth.

Furthermore, specialty controllers purchased through the Nintendo Switch Online program—such as the highly sought-after Nintendo 64 controller, the SNES pad, and the Sega Genesis control pad—sync perfectly to the new hardware for your retro gaming sessions.

Amiibo support remains intact. You can continue to scan your Amiibo figures using the NFC touchpoint on your controllers to unlock special gear in legacy titles like The Legend of Zelda: Tears of the Kingdom and Super Smash Bros. Ultimate.

Ring Fit, USB Accessories, and Third-Party Docks Warning

Standard USB accessories and the Ring-Con for Ring Fit Adventure are fully compatible with the Switch 2. However, a crucial warning for hardware longevity: Do not use older third-party Switch 1 docks. The voltage requirements and power delivery architecture for the Switch 2 have changed. Using an uncertified, older third-party dock runs a high risk of irreparably damaging (bricking) your new console.

Does Switch 2 Upscale Old Games? (Performance Boosts)

The Switch 2 is one of the Best Handheld Gaming Consoles on the market, rivaling devices like the Steam Deck. Because of this power increase, old games benefit in two distinct ways:

• Native Hardware Boosting: Unpatched Switch 1 games immediately benefit from drastically faster loading times and stabilized frame rates. Games that previously suffered from dynamic resolution drops will now hit their maximum targeted resolution constantly.
• Switch 2 Enhanced Patches: Developers can release software updates for older games. When you boot up an older title, the system checks for a "Switch 2 Upgrade." If available, the game will utilize the new hardware to output at native 4K (docked) and push frame rates to 60fps. Check the eShop for publisher-specific upgrade paths (some are free, others require a small fee).

Cross-Generation Multiplayer

Upgrading to the Switch 2 doesn't mean leaving your friends behind. Nintendo supports robust cross-generation multiplayer. If you are playing an older title like Mario Kart 8 Deluxe, Splatoon 3, or Super Smash Bros. Ultimate on your Switch 2, you can seamlessly play online with friends who are still using the original Nintendo Switch. Local wireless ad-hoc connections between the two console generations are also fully supported for compatible games.

What Happens to Nintendo Switch Online (NSO)?

Your existing Nintendo Switch Online (NSO) and Expansion Pack memberships carry over completely. By logging into your Nintendo Account on the Switch 2, you retain immediate access to the entire retro catalog.

You can redownload the NES, SNES, Nintendo 64, Game Boy, Game Boy Advance, and Sega Genesis apps directly from the eShop. All your cloud save states for these retro games will sync automatically.

What Happens to Unspent Nintendo Switch Game Vouchers?

If you have active, unredeemed NSO Game Vouchers, they remain securely tied to your Nintendo Account. You can still redeem them for eligible Switch 1 titles, and Nintendo allows them to be used to purchase select digital Switch 2 games, provided the vouchers have not yet passed their expiration date.
