Frontends are programs that allow a user to execute an emulator program, usually a command-line one, using a graphical interface. Examples of such are shown below.
Note: "Frontend" can be a somewhat confusing term since it is sometimes used to refer to an emulator's internal frontend that handles video, audio, and input interaction with the user and OS, while this page refers to the "Launcher" or "Executor" kind of "frontend".
