Actually this version number was displayed for neocd in the title bar until may 29th 2021, commit 90761c9f7afc679394d550c4eb4f5e6ef3b42358. The commit was not specifically about that but to fix an incompatibility between 2 games, I guess I probably took it off because I found it made too long titles which is probably true for a lot of games there.
Oh well since you are the most efficient bug finder around here I can put it back... !
