Console menu is a universal front end for console emulators running on the IBM PC platform. Just about any emulator that can be started with command line parameters will be compatible with menu.
Menu v1.9b is here, read all about it! (well you can after you've downloaded it!)
Menu is highly configrable, with lots of options. It will let you play roms directly from a ZIP archive, read the full game title out of GameBoy and Genesis / MegaDrive roms, make lists of your collection, allow you to sort your roms into directorys, plus many other features.
Download menu version 1.9b here.
