ForceHarmony lets the RPG Maker 2003 v1.05 or higher use a harmony.dll file as v1.04 and lower did. This will allow you to use patches which didn’t work with this versions until now, like Ineluki’s Key Patch.
Make sure there that a harmony.dll file is available in your project directory!
You will lose MP3 support when using Force Harmony, because the harmony.dll file doesn’t support MP3 playback. You can use Disharmony Audio Patch instead.
