Uhh, well that is not exactly how it works. They would have needed to build the game using appropriate resources for use on a PSX or PSX emulator to start with. They didn't. They used modern resources and made it look old. That's it. Unfortunately what you are asking / suggesting is that the developer go back and remake the "demake" again in old, outdated standards. It's just not going to happen. Sorry!

I apologize for any lack of clarity on my part. I was not asking for them to change how they’re doing things. I think it’s great how it is!
I was replying specifically to the “That’s why it’s a self contained application.” part. Maybe a bit confusingly, and pedantically on my part. Was just trying to say this isn’t strictly a requirement, nor a smoking gun. It being stand-alone is a hint that it’s actually a PC game w/ masquerading graphics (and I am well aware that this game is that, and was before I even came to the page). Just that it’s technically possible to skin an emulator so it looks like you’re running a single game natively.
But as you said, that would have required them to have actually made a PSX game to begin with. Which they didn’t. They made a PC game that just looks like a PSX game. It is in no way compatible. Totally get that on my end.
Maybe my clarification didn’t help the convo :)
