Another one is https://gaming.stackexchange.com/questions/tagged/game-ident..., but I don't know how popular stackexchange is these days.

They only allow questions with a video or image (not just from memory) which makes it unfriendly and of limited use.

They recommend /r/tipofmyjoystick or a selection of online chat rooms instead.

HN apparently works just as well. It's definitely Thexder and the voice is apparently saying "Thexder presented by Sierra" in Japanese as best we can puzzle out.

The quality is so terrible that even a native speaker had to listen to it several times and infer the rest from context, though.

To add to this, you can use https://www.reddit.com/r/tipofmyjoystick/ for video games specifically
