'''Frontends''' are programs that address a quality-of-life issue that emulators may not fulfill. For example, some emulator developers skip the user interface portion of development by having the user launch them from the command line. This usually means opening Command Prompt in the folder where the emulator is installed and typing something like <code>emulator.exe game.rom</code>. From a usability perspective, this is not optimal; running emulators from a shell can be considered tedious if commands aren't already scripted by the user (and they can't be expected to know how to set up such a thing if their first time loading the program is a black window that pops up and then disappears). To avoid this, many emulators will try to incorporate some kind of ''graphical user interface (GUI)'' in their standalone builds. For the emulators that never receive one however, a separate frontend project usually emerges.
