Burning Force arcade PCB (1989) - which runs on the Namco System 2

The Namco System 2 is a 16-bit arcade system board that was first used by Namco in December 1987, and a major enhancement for their earlier Namco System 1 arcade system board (which was introduced in April of that same year); it was later succeeded by the 3D Namco System 21 "Polygonizer" arcade system board, in 1988.

Final Lap was the first game to use this board, and also the first to allow up to eight players to play simultaneously, when four two-player cabinets were linked together; the following year, six more games using this board were released, which were Assault, Assault Plus, Ordyne, Metal Hawk, Mirai Ninja and Phelios. In 1989, they released Valkyrie no Densetsu (the sequel to Valkyrie no Bōken: Toki no Kagi Densetsu), Dirt Fox, Finest Hour, Burning Force, Four Trax, and Marvel Land - and, in 1990, they released Kyūkai Dōchūki, Final Lap 2, Dragon Saber, electromechanical Golly! Ghost!, Rolling Thunder 2, and Steel Gunner. For 1991, they released Super World Stadium, Steel Gunner 2, and Cosmo Gang the Video (which featured characters from a "redemption" machine); in 1992, they released Bubble Trouble: Golly! Ghost! 2, Suzuka 8 Hours, Super World Stadium '92 (and its Gekitōban variant), Final Lap 3 and Lucky & Wild. Then, in 1993, they released Super World Stadium '93 Gekitōhen and Suzuka 8 Hours 2, and the board was retired after six years.
