About this project

A static recompilation of version 11.0.0 for Windows: the game's AArch64 code is translated to C ahead of time and runs on its own runtime, with a Direct3D 11 renderer that translates the Switch's shaders and caches them. A prebuilt runtime is in the releases, so you only point it at your own game files; later versions such as 13.0.5 can be built from your own update. Online play carries the game's Local Wireless mode over a relay, through a public lobby or private rooms. One player per PC for now, and full two-PC matches and the whole roster haven't been fully checked. An experimental Linux build runs through DXVK.

What you need

Your own Super Smash Bros. Ultimate RomFS (version 11.0.0, or a later update you build yourself) and the Switch's firmware fonts, Windows 10 or 11, a processor with AVX2, FMA and F16C, and a Direct3D 11 graphics card.

About this project

A static recompilation of version 13.0.4 into a native Windows program with its own runtime and Vulkan renderer. Early and playable in parts: the opening movie, title and menus work. It also turns the fighters' scripts back into readable code (95% of their animation scripts so far) and can add new fighters as copies of existing ones. Linux and the Steam Deck aren't started, and there's no release yet.

What you need

Your own dump of Super Smash Bros. Ultimate updated to 13.0.4, and Windows. No download yet: you build it yourself.

Decompilation
About this project

A matching decompilation of patch 13.0.4, the final version: 14,156 of 39,635 functions decompiled and 26.2% verified byte for byte, but only 1.8% of the code by size, since the matched functions are mostly small ones. No commits since April 2026. No playable build; SSBU Recomp is the one that runs.

What you need

No build to play. It works from patch 13.0.4.
