NO you can not. A PC Emulator includes a PS2 Bios so it could not be called solely on a computer. Not that I know if you can use it to get on the Playstation Network. Any PC can access the Playstation network that is available for the PC and it is not the online games section that is available, but the support section. A PC could not even play a PS3 game and the Playstation Network would not work with a PC game as they are not compatible.
To get games that are available on the PlayStation Network (PSN), you'll need a PlayStation console, such as a PS4 or PS5, and a stable internet connection. You can access the PSN through the PlayStation Store on your console or via the official PlayStation website. From there, you can browse, purchase, and download games directly to your system. Additionally, some games may be available through a subscription service like PlayStation Plus or PlayStation Now.
