Is it possible to use a playstation save on a pc version?
No, it isn't. The PSX emulator's save is one of two things:
- A savestate - a dump of the emulated PS1's RAM.
- A virtual memory card - A file representing a PS1 memory card.
Understandably, neither of these are readable by a PC game.
On top of that, even if it was possible to extract the game's save from a virtual memory card, there is absolutely no guarantee that the format for the PC version is the same. It's more likely that it was changed during the port.
