Emulators are computer software which enable you to play video games from other platforms on your PC. The newer the platform you want to emulate the better PC specs it will require. Generally if you have a modern computer (recent generations of Intel i5/AMD Ryzen 5) you should be able to emulate all platforms tagged on this website with the exception of more demanding PS3 titles.
