Because of my renewed interest in Z80 and wanting to better learn assembly programming, I ultimately want to do a bit with Game Gear/SMS coding. For this though, an emulator with at least some basic debugging facilities would be useful. After searching Linux Game Gear emulators, none really had what I was looking for. On my first attempt, I decided Dega looked interesting, it has source available. The two major turn offs of Dega was the Z80 core which is x86 assembly, which is obviously not portable and it’s license which basically says, do what you want to the source, as long as it’s not sold.
