Writing a 6502 Emulator, part 2
Published:
Last week, I set up the beginnings of a 6502 emulator, including the core codebase. Unfortunately, a command line application that just runs 6502 assembly code is super hard to debug. The 6502 isn’t equipped with any way to print output by default (unless you’d hook up a 65C22 VIA, but coding that seems tricky), and reading raw bytecode isn’t the easiest thing to do. Other emulators I’ve used (ex. Symon) include a pretty nice GUI to debug applications. I didn’t want to go as far as writing a whole application frontend, but I did think implementing some kind of updated UI would be a great addition for both users and for my personal debugging.
