4 free open source game emulators for Windows PC, Linux and macOS

The emulator is 100% legal, just like torrenting, it's also a client download. Emulators are no different from other programs you can download like word processing software or music players. However, downloading and uploading ROMs is illegal, so make sure you use your own game files. You are only allowed to use the emulator provided you have a legal copy of the game, be it soft copy or CD format.

These emulators work pretty well. However, if you have a mid-range computer, you may experience some lag when playing continuously. These emulators also come with control handle mappings. All games work on keyboard and mouse, ideal for those with lots of old Playstation discs. Of course, things can change depending on the game you're playing.
