Astris
What it is
Astris is a free, open-source Nintendo Switch 1 emulator based on Ryujinx for Apple silicon Macs. The project README specifies macOS 15 or later, and binaries are distributed through its repository, with releases also published on Codeberg. Astris supports resolution scaling, motion controls, and Vulkan and Metal graphics APIs. Its library can accept game updates, downloadable content, and mods by drag and drop, while a cache is intended to improve scanning of external drives. An option can disable host V-Sync to reduce presentation delay, though screen tearing may result. Release 1.0.23 adds per-game graphical enhancement controls in the Game Overlay on macOS 26 or later, with changes that can be restored. The same release addresses a possible MoltenVK out-of-memory crash, controller input for devices connected before launch, and launch or gameplay crashes affecting listed games. The repository links an MIT license, is owned by V380-Ori, and acknowledges Ryujinx and Ryubing contributors. The project states that it is not affiliated with Nintendo.
