I've been using D-Fend Reloaded for years now as my game launcher. It is by far the best DOSBox front-end I've found and it's configurable as a front-end for all other systems, emulated or not. Everything goes into D-Fend Reloaded: DOS games, Windows, Steam, SCUMMVM, NES, Genesis, TurboGrafx, Atari, TRS-80, Magnavox, MESS, MAME, browser games, etc. It pulls information from Mobygames (and other sources now) and populates preview/screenshot folders and other miscellaneous data fields like publisher and release date. Then you can sort everything by genre, or emulation type, or mark favorites, search titles, and filter by other pieces of data if you've pulled them from Mobygames. Each game profile also comes with a spot to store your manuals, walkthroughs, and other documents. Setting up extra program files (i.e. cheats and map editors) for a game is also provided. This is a really feature-rich launcher and I'd be lost without it.
