I just double checked, and it didn’t have any, it looks like. So it’s just the PS3 Slim that cut backwards compatibility.
As for why the PS4 wasn’t backwards compatible with PS3 games, the PS3’s architecture was hard to emulate and too expensive to include wholesale without ballooning the price beyond the target.
The PS2 and PS5 slim versions didn’t mess with backwards compatibility, just the PS3
and PS4.What backwards compatibility did the original PS4 have?

Thanks for the correction. I typically avoided the slim versions myself.
