Minigsf: To Midi Verified

| Pitfall | Cause | Verification method | |---------|-------|---------------------| | Wrong pitch (off by semitone) | Incorrect frequency-to-note formula (e.g., using A=440Hz vs. GBA’s actual master clock) | Compare a simple sustained tone in both original and MIDI with a tuner | | Missing delay/echo | GBA hardware effect not representable in MIDI | Spectral analysis: re-synthesized MIDI will lack tail energy | | Muted percussion | Drum samples mapped to wrong MIDI note | Check that all drum notes (MIDI 35-81) actually appear in a percussion channel | | Tempo drift over long tracks | Cumulative cycle-to-tick rounding errors | Compute average tempo over 10-second windows; drift should be <0.5% |

The process of ensuring the resulting MIDI file matches the original game track in terms of tempo, note duration, and channel mapping. 3. Conversion Methodology minigsf to midi verified

: If a game uses a custom driver instead of the standard Sappy engine, automated tools may fail. In these cases, manual logging via an emulator with MIDI-out capabilities is the only verified fallback. Useful Software Links | Pitfall | Cause | Verification method |
