Yes, you can play PPSSPP games on a PC. The PPSSPP is an open-source PSP emulator, which means it's designed to mimic the functionality of the Sony PlayStation Portable on other devices like a PC or smartphone. It allows you to run PSP games in full HD resolution on your PC. To do this, you must install the PPSSPP emulator on your PC, which is available for several operating systems, including Windows, MacOS, and Linux. You will also need PSP game files or ROMs, which are the games themselves. It's important to note that you should only download or use ROMs for games that you legally own.
