I've gone deep in the hole on Z80 emulation more than a few times as a result of my all-time favorite video game (Phantasy Star on the Sega Master System). I wrote some debugger emulators just to step through the game's code and analyze it. If you've never tried to write an emulator I highly recommend it. In my opinion it's an exercise on par with writing a compiler, in terms of how much one can learn about these machines we work with and just developing a richer appreciation for the craft of software.
