@HihiDanni I don't do any game dev myself, but here's something I think ya'll might be interested in or might serve as like as a gateway for getting into this kind of stuff.

This is a way/program to get Twine games working on the Sega Master System and Game Gear, and even be able to add pictures. So you can basically make visual novels/choose your adventure games that'll work on those two systems.
