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 Continue reading →

Z80 Assembly

I’m currently learning Z80 assembly (I’ve read the book once, but now I’m actually working through the exercises.) I have to say, it’s fun and a bit challenging at times. The challenge is partly learning the tools. I’m currently using z80pack. From that I’m using z80asm and z80sim. I’ve played a bit with the cpm2&3sim emulator that comes with it, but I currently only really need z80sim. z80asm can be a bit strange at time (or perhaps just more strict then the book.) For instance, Continue reading →
