I love these tiny VM's, thanks to emulation I'm there since two decades.

On a Chip8 interpreter written in AWK and a bit of help of coreutils (to mimick getchar in C to pick a single char; if you can do it under AWK without resorting to GNU od or read, kudos):

OpenBSD and the rest of BSD users: you need to install 'coreutils' from ports, open 'dale8a.wk' and 'tgl.awk' and rename 'od -' to 'ggod -' .

Proof that it works:
