I had more luck with a little experiment a few days ago: I took phone pics of one of the shorter BASIC listings from Tim Hartnell's "Giant Book of Computer Games" (I learned to program out of those back in the early 80s, so I treasure my copy) and asked Gemini to translate it to plain C. It compiled and played just fine on the first go.
