Looks like I was probably wrong about this. There are a lot of "doom running on a vape" videos on YouTube - very easy to find, that's what search is for - but the best primary source I could find quickly actually has doom running separately and the vape just being used as a display.

Search for something like "doom on Puya PY32"
