4 Free Open Source Game Emulators For Windows PC, Linux, and macOS

Home » Freeware and Software Reviews

Emulators are 100% legal, just like torrents, as is the process of downloading the client. Emulators are no different to other programs you might download such as word processing or music player software. Downloading and uploading ROMs is illegal, however, so make sure you use your own game files. You are only allowed to use an emulator provided you have the legal copy of the games, be it in soft copy or CD format.

These emulators work pretty well, however, if you have an average computer you’ll probably get some lag while playing intermittently. These emulators come with controller mapping too, all the games work on a keyboard and mouse. Ideal for those with many old playstation discs.

I don’t have any real complaints other than the periodic lag; it’s that good. Of course, your mileage may vary depending on the game you are playing.
