What Astris is
Astris is a Nintendo Switch 1 emulator based on Ryujinx for Apple silicon Macs. The project README specifies macOS 15 or later, and the repository distributes binaries, with releases also published on Codeberg. The project lists support for resolution scaling, motion controls, and Vulkan and Metal graphics APIs. Release notes describe adding updates, DLC, and mods to a game library by drag and drop, along with a cache intended to speed scanning on external drives. An option to disable host V-Sync can reduce presentation delay, with possible screen tearing as a trade-off. Release 1.0.23 adds per-game graphical enhancement options in the Game Overlay on macOS 26 or later, with changes that can be restored. That release also fixes a possible out-of-memory system crash when using MoltenVK and controller input for devices connected before launch through LaunchServices. Its listed game compatibility changes address crashes for several named games. The repository links an MIT license. The project states that it is not affiliated with Nintendo.
