What's new
Linux internet netplay sign-in now tries available browser launchers in sequence: WSL wslview when applicable, then xdg-open, gio open, and sensible-browser. The AppImage preserves the host library path for those helpers. Two-player Link Cable netplay remains available.
Download the Windows x64 ZIP or Linux x86_64 AppImage below. Supply your own Mario Kart: Super Circuit (USA) ROM and GBA BIOS; neither is included. SHA256SUMS.txt lists both download hashes.
Validation: 25/25 recomp-net tests under WSL, framework multiplayer netplay tests, and packaged 1,500-frame full-static smoke runs on Windows and Linux. Live Discord OAuth was not exercised in this environment.
