Behavior change: PlayStation controllers (DualSense / DualShock) now confirm with × and go back with ○, matching the Xbox layout. To keep ○ as confirm, choose "By position" under Controller Button Mapping. Same on iPhone / iPad and Mac.
Since 0.2.3, Switch 2 games opened in English on Chinese systems; they now follow the system language. Language selection for Switch 1 games is unchanged.
What changed
- Fixed some games (such as Hades II) exiting on iPhone during voice audio: when hardware voice decoders reach the limit the request is now declined gracefully, as on original hardware. Not yet verified on the reporter's game version; if it still happens, please export a diagnostics package.
- On Windows, moving the game library during an upgrade occasionally left files behind; it now moves once, and if a file is in use the library is used as-is and moved on the next launch.
- Some games exported with zero precompiled shaders (more stutter on first play); they are now precompiled correctly and need to be exported again. The completion page now warns when precompilation is empty.
- Games in the library can be reordered by dragging; on iOS 26 / macOS 26 floating buttons use the system Liquid Glass material (can be turned off in Settings); s2arm.com is now the official website.
