Most recent example I can think of is the Mega Man ZX games in the Mega Man Zero/ZX Legacy Collection, which are PC ports of old NDS games. The cutscenes just show a white screen. Did manage to fix that thanks to someone’s help on reddit (was related to mfplat and another component iirc), but there are also instances where that won’t work (I tried to help someone fix a cutscene issue on an obscure visual novel, but I couldn’t get that to work if my life depended on it).
Modern games do seem fairly safe though, like you said.
That’d make it even stranger, like wouldn’t that reliably always fix the issue, since that’s the actual dependency? It looks a bit like it’s not entirely completely somehow though.
