Who likes emulation? In today's guide, I will be showing you how to get the Lemonade 3DS emulator up and running on your Steam Deck. Let's get right into it.
First things first, you'll need to download the Lemonade 3DS emulator from GitHub. Open up your browser and search for "Lemonade 3DS emulator." Click on the GitHub link and then click on the Alpha 2 option. Scroll down and download the Linux app image.
Next, extract the folder and run the executable. To get your controller to work, you'll need to go to the controller settings and choose auto-map. It will then detect your Steam Deck controller, and you'll be good to go. If you want motion touch, you'll need to get it through Emudeck. Install Steam Deck Gyro DSU, open up Lemonade again, and go to motion touch. Make sure you have the CemuhookUDP selected for motion provider, and then test it. Once you've tested it, hit okay, and your controller should be set.
Now, let's talk about how to bring this emulator to Steam OS. Open up ID deck, click on Steam R manager, and then choose classical steam mode. Create a parse and then scroll down until you find Nintendo 3DS. Select your ROMs directory and choose where you want your ROMs to come from. After that, select the app image that you saved in the desktop and hit save.
Switch back to Emudeck and go to preview. The games that you have in your 3DS folder should come up here. Save it to steam, and you should be able to run it on Steam OS or game mode. To check if it works, go to your library, click on non-Steam games, and you should see Super Mario Bros and Mario Kart 7. Click on play, and it should boot up.
