I was thinking that this was included in the Apple ][ Integer BASIC ROM, but when I checked it was Woz’s own special instruction set, SWEET-16 which gave compact (if slow) ability to do 16-bit coding on the 6502.

These sorts of things are loads of fun to implement to get a closer feel to bare-metal programming. XKCD published a 16-bit “CPU” machine language 15ish years ago and I remember everyone was rushing to do code golf implementations of it, although I think a slower-paced approach to the project is better for the educational aspects.

When I was writing my own CHIP-8 emulator I struggled to find info on timings as info on the COSMAC VIP was scarce. I resorted to arbitrary sleeping which solved most of the issued for the roms I tried back then.

It had a JIT recompiler based on sljit.

The author runs his own chip8 game jams which is pretty fun. He also runs his own webcomic: https://beyondloom.com/comic/index.html

The comic was last updated a decade ago. I've added it to my RSS feeder without getting my hopes up. I was really getting into the story too.
