[cctalk] qbert license?

Perhaps slightly off topic, but perhaps someone here has a contact or idea on how to get started on this: Someone has done a Q-Bert port in 2023 to a new system. The title is different, but the "look and feel" (and audio) is pretty "authentic" to the original (not sure if using exactly the same original tiles and such, I believe it was all original work - but still, it's very much an arcade-style clone). We see now that Sony "owns" it these days (I seem to remember decades ago there a Q-bert cartoon? But perhaps remembering it wrong). The question is, how would one start on obtaining a license? I assume it wouldn't be cost effective (for a free casual port), but still just curious. I've tried to contact Sony in the past (on a different software title), but it's just a huge enterprise it's a bit challenging to approach. Just wondering on the off chance if maybe someone around here has gone down this road already? -Steve
