Erika to Satoru no Yume Bouken is one of few games to utilise all 8 channels of the N163’s expansion audio. However, this game neglects to clear all of the Sound RAM on power-on and plays uninitialised waveform data. This causes the accompaniment in the title music to sound buzzy on some power-ons. The behaviour is currently only seen on real hardware and FCEUX (with random RAM initialisation). The author has reported the inaccuracy to Mesen-X & puNES’s issue trackers, so they should implement the correct behaviour soon.

This hack fixes the reset handler so that the Sound RAM is properly cleared, ensuring the title music sounds correct regardless of initial Sound RAM values. The author has not tested this with any translation patches, so there is no guarantee that it will be compatible.
