Oh dear, it seems we've... somehow been psychically linked...

I developed a browser-based CP/M emulator & IDE: https://lockboot.github.io/desktop/

I was going to post that instead, but wanted a 'cool demo' instead, and fell down the rabbit hole.

That is beautiful.

I wrote a console-based emulator, and a simple CP/M text-adventure game somewhat recently

https://github.com/skx/cpmulator/

At some point I should rework my examples/samples to become a decent test-suite for CP/M emulators. There are so many subtle differences out there.

It seems I could even upload a zipfile of my game, but the escape-codes for clearing the screen don't work, sadly:

I've been playing the Z80-μLM demos in your CP/M emulator. Works great! However, I have yet to guess a correct answer in GUESS.COM! I'm not sure if I'm just not asking the right questions or I'm just really bad at it!
