Wario Synthesis Engine: Convert MIDI Files to Game Boy 8-Bit Music in Browser
By

Best dunked in coffee. Better still, swap for a fresh one.
Summary
The Wario Synthesis Engine is a web-based tool that converts MIDI files into Game Boy-style 8-bit music. It analyzes MIDI files to identify melody, bass, and chord tracks, then resynthesizes each part using Web Audio oscillators tuned to mimic the Game Boy's 4-channel sound chip (two pulse wave channels, one wave channel, and one noise channel). The tool runs entirely client-side in the browser without server-side audio generation, built with TypeScript, Vite, and Claude Code. Recent updates include MP3 download functionality, offline rendering for faster exports, and 16-bit to 8-bit conversion capabilities.
