Silly question, I know, but are any of these "PS1" games actually playable on a Playstation/emulator?

These are not PlayStation games, these are in the style/inspired by the PlayStation. They are for the PC.

I would love somebody to actually make PS1 isos like this. but it would be too much of an effort to port them over if they were made without that inmind in the first place.

I believe the PS1 hardware couldn't handle some of these guys, but it would be 100% awesome. I was thinking about that while playing Pathogen X and Loveland.
