Hack description

An obscure bug in the sound driver causes the music and sound to malfunction slightly on Gen/MD hardware that has a discrete YM2612. This patch fixes the stuttering sound and music that can occur on a Model 1 Genesis or Model 2 with a YM2612. It also adds in a cheat code for a new sound test function and removes the region protection. This patch is mainly intended for flashcart/Everdrive users with Model 1 consoles.
