If a game is low spec enough to run on a PS4, it typically has a PS4 version as far as I can tell, but maybe there are exceptions I haven’t kept up with. And in order to have a handheld PlayStation that doesn’t require its own versions of games like the Vita and PSP did in the past, the best they can really hope for is a PS4. That’s why this problem seems insurmountable unless they go the PC route like everyone else.
