This is a big step in emulation! Getting retail games to boot is no simple task. The emulators Ryujinx and yuzu have gotten several screen transitions and some layers to show, but there is still lots more to reverse engineering to go. These emulators are a great tool to test your own Switch homebrew on, if you’re considering working on that. Especially if you’re on a higher firmware or don’t currently own a Switch. As some people might be waiting for the Custom Firmwares, Atmosphere and Fusée Gelée.
The three games that are able to launch currently are Cave Story+, The Binding of Isaac: Afterbirth and Puyo Puyo Tetris. You can view their up to date compatibility page at https://github.com/gdkchan/Ryujinx/wiki/Games-Compatibility-List
