So, you can have a Windows PC and install an emulator to play arcade games like Pacman. An emulator is a piece of software that you install onto one machine which emulates a copy of another operating system so that you can play games or run other software. Have you ever wanted to play classic arcade games from your sofa? If you are a Kodi user, then by installing add-ons and some software you can play hundreds of games for free through emulators.
