RomCenter v4.0.0 is released. RomCenter is an application written for 32-bit Windows operating systems, designed to help you maintain and organize your emulators roms collection for various gaming systems including computers, consoles, arcade, calculators and handheld. You can add additional systems through external datafiles available on a lot of sites.
