Super Smash Bros Ultimate PC port arrives unofficially. Fans are getting options to play the title on PC via static recompilation. Two projects turn the Nintendo Switch ARM64 code into native Windows programs, without real-time emulation.
What happened?
WindowSmash, by SNO2207, and OpenSmash-Ultimate (ssbu-recomp, by Denkishi) recently arrived as native ports. Both require the player to provide their own legal dump of the game, obtained from their own Switch, along with console keys. Neither includes game files.
Static recompilation translates the Switch code to C once, before execution, and compiles it for x64. The runtime reimplements console services such as graphics, audio and input.
WindowSmash
Focused on version 11.0.0 (with tests on 13.0.5), it uses Direct3D 11 and supports keyboard, XInput controllers and up to eight gamepads. It includes experimental multiplayer that relays the game's Local Wireless over the internet. It has ready packages in some versions and builds of about 30 GB. The project is in alpha.
OpenSmash-Ultimate
Targeting version 13.0.4/13.0.5, it uses a Vulkan renderer and reports 59-60 FPS in matches on NVIDIA GPUs and Intel integrated graphics. It allows 1v1 matches against CPU up to the results screen, Classic Mode and Training. The developer indicates that almost all of the code was written by AI agents (Claude) under human direction. Build takes about 45 minutes.
Why does this matter?
Smash Ultimate never had an official PC version. These native ports potentially offer lower input lag and better performance than traditional emulators, plus support for higher resolutions and PC controls. They are still experimental, with multiplayer limitations and bugs. Nintendo is not involved and may take legal action.
