Spec score 7.6 #10 of 20 in Nintendo Switch Emulators

What it 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. It is free and open source under the MIT license. Astris supports resolution scaling, motion controls, and Vulkan and Metal graphics APIs. Releases describe drag-and-drop addition of game updates, DLC, and mods, plus a cache intended to speed scanning of external drives. An option can disable host V-Sync to reduce presentation delay, with possible screen tearing. Release 1.0.23 adds per-game graphical enhancement settings in the Game Overlay on macOS 26 or later, and includes a possible MoltenVK out-of-memory crash fix and controller launch-input fixes. The same release lists compatibility fixes for several named games and updates KosmicKrisp and MoltenVK. The project is owned by V380-Ori and states it is unaffiliated with Nintendo.
