## What is WindowSmash?
A Nintendo Switch and a Windows PC have different kinds of processors, so a Switch game can't run on a PC as it is. An emulator solves that by translating the game *while you play*. WindowSmash translates it **once, ahead of time**: it turns the game's code into C, compiles that into an ordinary Windows program, and adds a runtime that gives the game what it expects from a Switch: graphics, sound, controllers, files and networking.
The game itself still comes from your files. This repository holds only the translator (the *recompiler*) and the runtime.
**What you get**
- **Up to eight controllers**: Xbox, PlayStation, Switch Pro and most others, plus the keyboard.
- **Windowed, borderless or full screen**, always 16:9, with settings for G-Sync and FreeSync monitors.
- **Online play through Local Wireless**: rooms appear for every player in the online lobby, and nobody has to set up their router.
- **The game's own Online mode**, new and still being tested: Quickplay against WindowSmash's own game server.
- **Your DLC fighters**, and a tool that unlocks the base-game roster on your own save.
- **Any game version**, including 13.0.5 with Kazuya and Sora, and several versions side by side.
- **An experimental Linux version**, built from the same source: `install-windowsmash.sh` sets it up on Linux in one go (Linux).
- **An experimental macOS version** for Macs with Apple silicon, built from the same source: `Install WindowSmash.command` sets it up on the Mac in one go (macOS).
