Because legacy chips often used micro-tuning, converters like vgm2midi by Ben Ryves use the MIDI pitch wheel to maintain accuracy. Popular Tools
Video game chips didn’t just play notes. They played sound effects. They used "arpeggios"—rapid-fire loops of notes played so fast they simulated a chord on a chip that could only play one note at a time. They used raw PCM data (drum samples) that looked like static to a music program. Vgm Midi Converter
