Astris vs Strato

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.

Strato is a free, open-source experimental emulator for ARMv8 Android devices. It aims to reproduce Nintendo Switch system functionality through an ARM Compatibility Layer and System Emulation, with goals of accurate, performant and user-friendly operation. The project remains in development and is not ready for public release. Work has covered texture management, synchronization, queries, MSAA rendering and the blit engine, including a texture-manager rewrite intended to improve rendering accuracy. A texture-variant system improved compatibility with Mali GPUs, and firmware importing supports games that use firmware assets. Developers were also modifying core components for 32-bit games, with that work still ongoing in a February 2024 report. Its shader compiler is a modified fork of yuzu’s compiler for mobile GPU emulation. Strato began after Skyline ended in May 2023. Lynx and TheASV are named developers, with additional contributors. The source is licensed under GNU GPL v3.0 or later.
