Wario's own tunes, pushed through a Game Boy sound chip.
Each link searches for a MIDI of the track and opens it in Wario Synth. Pick a source, hit Generate, and it plays as 8-bit Game Boy chiptune. Save it as WAV or MIDI if you like it.
The name started as a joke about a synthesis engine that's loud, greedy and slightly wrong. It stuck. The engine itself is generic: it takes any MIDI, splits melody, bass, chords and drums, and maps them to the four channels of the original Game Boy. Wario just happens to be its mascot — and his games had some of the best chip music Nintendo ever shipped.
Type any song title on the home page, or upload your own MIDI. Everything runs in your browser; nothing is stored on a server.
Is this official Nintendo music?
No. Wario Synth is a non-commercial fan project. It searches public MIDI transcriptions and re-synthesises them; nothing is hosted here.
Why does a track sound wrong?
MIDI transcriptions vary. Pick a different source in the results list — some are much better than others.
Can I get the file?
Yes. After Generate, Save Audio gives you a WAV and Save MIDI gives you the 4-channel arrangement.
What about non-Wario songs?
Anything. Type any song title on the home page.
