In 1990, the Top Game, manufactured by CCE, was released; it sported a dual cartridge slot, allowing games in the 72-pin American cartridge format and the 60-pin Japanese cartridge format to be played. The BitSystem, also using the American cartridge format, was manufactured by the now-defunct company Dismac. The Phantom System was released in 1991 by Gradiente, and was the most popular Brazilian Famiclone; the console body resembled very closely the Atari 7800, and its controllers were clones of those of the Sega Mega Drive.
