So basically everything will work with BC? (what people assumed to be the case anyways)
If these are the only confirmed games that wont run:
"Here’s the full list of non-compatible titles:"
Afro Samurai 2 Revenge of Kuma Volume One TT Isle of Man – Ride on the Edge 2 Just Deal With It! Shadow Complex Remastered Robinson: The Journey We Sing Hitman Go: Definitive Edition Shadwen Joe’s Diner PS3 PS2 PS1
And some of these are getting patches to fix their issues so they might possibly work in future on PS5? Meh, just shows how overblown that "concern" about PS5 BC was.
