MPAGD runs on Windows. AGD runs on the ZX Spectrum, so you would need an emulator for that.
Thanks. Then AGD is for me, I'm mostly on macOS or Linux. I want to create a CTF challenge where the player first must realise (s)he should load the tap-file into an emulator, then solve the game to get to the secret flag, which is just a text string that proves you solved the challenge. So I'll use AGD to create the tap-file.
