The Sudachi Emulator is a software that allows you to play Nintendo Switch games on different devices. To play Nitendo games, you need a Nintendo Switch console to play these games, but with this emulator, you can run the games without the actual console. It works by making your device act like a console. To use it properly, your device needs to be fast enough, and sometimes you might need to change some settings to make the games run smoothly. It’s similar to other programs that let you play console games on your device.
