I can top that :) (although it hasn't been used in a production emulator)

I wrote this a few years ago - it's ~500 lines taking advantage of the logic behind the instruction set (instead of a jump table) and it can run Apple I BASIC at least.

Looks really clean. Nicely done.

That is similar to my approach to emulating the Gameboy Color's Z80-like CPU. Not yet completed - probably never will be :(

Yeah, imo trying to actually do some instruction decoding rather than just a massive switch case is a lot nicer.
