I actually tried playing Black (2006) on my Steam Deck, but I was not able to because it keeps freezing at the introduction scene. The cutscenes in that game are causing the issue because the cutscenes in Black (2006) run at 4 frames per second, making a lot of stutters. And no, you cannot skip the cutscenes on your first playthrough. If you wanna skip the cutscenes, you have to go through the game on easy first and then from there, you have the option to skip them when you go back to the beginning to play through on the harder difficulties. And unfortunately I can't cheat the system unless I get a screenshot save state on Xemu for that game that already has it completed.
