Oh yeah, this is a bubble, but fwiw, there should be minimal compatibility issues possible from my understanding as this is essentially the change disk mechanism we see in several games, but without the check that the correct disk has been inserted. Of course there'll be edge cases (and I'm gonna imagine there might be some late stage additional copy protection in some games that doesn't rely on the boot up checks), but on hardware as simple as the playstation it's going to be pretty much: if you're running the executable, you're running the game as if it's passed the checks
