Dempa Shimbunsha

Dempa Micomsoft was the software division of publishing company Dempa Shimbunsha. In 1993, it was broken off as a separate company, though fully owned by Dempa.

Apart from programming games, with Dempa earning a high reputation for its arcade conversions, it also made joysticks and other hardware. The company now remains as Micomsoft Co., Ltd., with TV scan converters as its main business.
