I also had the idea of remaking Chemical Plant Zone from Sonic 2 Genesis in Game Gear arrangement.
I even made a custom sample based on the V3 Game Boy along with a custom icon too.
Unlike my Emerald Hill Zone remake, White noise is now used instead of cymbals for the 4th noise/DAC channel.
I’m going to clarify that as far as I remember the 4 channels of the Game Gear/Master System’s sound processor each only have a single note polyphony, so I have to play by its rules. I think I pulled that off pretty well.
