About a year or so back I got a book that the public library was giving away after a book sale on Z80 assembly. I read it, but never really did anything with that knowledge. The thought was always in the back of my head to eventually apply that and play around with some SEGA Master System/Game Gear coding. Unfortunately time has a way of getting away from you. The library had a book sale about a month or so back and they had quite a few books.

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.
