# PolyGame Master

The PolyGame Master (PGM) is an arcade system board released in 1997 by the Taiwan company IGS. The PGM was developed in order to compete with the likes of SNK's Neo Geo MVS system in Taiwan. It was succeeded by PGM2 in 2007, and PGM3 in 2012.
DoDonPachi DaiOuJou, released by CAVE, came on a single dedicated board and utilizes a customized BIOS programmed by CAVE. Ketsui and Espgaluda, again released by CAVE, came on a single dedicated board, but did not have a separate BIOS, as these functions are integrated into the main program.
