Do you know how to program game boy games on mac
I'm not sure you are on itch anymore. But if you come back, don't stop. Pursue the dream. I develop on Linux and occasionally Windows. I avoid high entry costs and proprietary stuff. But Mac has similarities to Linux. RGBDS and BGB are a rough route. Renpy might be a good intro for gameboy looks and you could create sprites and an interface that is gameboy green. Good luck.
