Nice work and thanks for sharing. I'd like to add this blog post [1] I read a while ago that explains a bit how to write a disassembler and emulator for Chip-8. The source is not as clean as yours and written in C but it's still worthwhile to check out.

I wrote a disassembler as part of my own Chip8 IDE[1]

It doesn't look like it impacts this disassembler, but it's worth noting that Cowgod's Chip8 technical reference gets the shift and load/store instructions wrong. A much better reference is Mastering Chip8[2].

Thanks-- my code isn't the cleanest either! I still have a lot of cleanup to do. I will certainly check it out though!

Thanks-- I will certainly look into those instructions
