The "Unbeatable Song Hack"

Most likely the first mod menu for the Unbeatable DEMO.

To use, download MelonLoader ( https://melonwiki.xyz/ ) and put a .dll of this mod into the Mods folder. A GUI should pop up.

Developing this

If you want to work on this, you should most likely replace all the <HintPaths> in UnbeatableSongHack.csproj with your paths to the game, as well as the <Target><Exec> at the bottom of that file.
