The Firecore is a system-on-a-chip clone of the Sega Genesis/MegaDrive system. It was announced as the Sega Genesis 4, a remodeled Sega Genesis console that featured built-in games. The system is manufactured by ATGames. The console does not have an expansion port, which makes the Firecore incompatible with the Sega CD. It is also not compatible with the Sega 32X. Another problem that the system has is the poor reproduction of the original sound, especially if the in-game music when it is played from the original game cartridges.
