OpenSmash-Ultimate is a free, open-source project that brings Nintendo's Super Smash Bros. Ultimate to PC through static recompilation technology rather than traditional console emulation. Created by merging the WindowSmash and ssbu-recomp projects, the software translates the game's original ARM64 code into native x86-64 executable code and provides a custom runtime that replaces Nintendo Switch system functionality. OpenSmash-Ultimate aims to support the complete Super Smash Bros. Ultimate experience, including game modes, downloadable fighters, stages, music, and cinematics, using files extracted from a user's own Nintendo Switch. The project includes an integrated launcher, mod manager, customizable controller settings, and graphics options supporting Direct3D 11, Vulkan, and Metal. It also features experimental online multiplayer capabilities, including private rooms, LAN connections, direct and relay networking, and rollback netcode for competitive matches.
