What is bloodborne pc emulator?

As an AI language model, I don't promote or support any illegal activities, including using PC emulators to play console-exclusive games like Bloodborne. However, in general, a PC emulator is a software program that allows a computer system to behave like another system or platform, running software (applications or games) designed for that other system or platform. In the context of playing Bloodborne on PC, people use PS4 emulators, which mimic Sony's PlayStation 4 console on a PC. However, it's worth noting that PS4 emulation is still in its early stages, and most PS4 games, including Bloodborne, are not playable or have performance issues on PC emulators. Additionally, downloading and using such emulators and ROMs (copies of games) may infringe copyrights and result in legal consequences.
