A Windows launcher and mod framework for Steam Happy Wheels 1.99.2.

You need a legal Steam copy of the game. This project never ships Happy Wheels, Happy Wheels.exe, or app.asar.

• Install (players)

The public source for the launcher and SDK is github.com/MathewRegier/jhwml.

Happy Wheels internals are obfuscated and locked to Steam 1.99.2. A game update needs a new launcher. Other mods should use window.HWMod, not webpack module numbers.
