A subsidiary of the Daou group. They first got known as an official distributor for some MSX/Zemmix products, and later became the country's major publisher of 8-bit console games under the label Jaem Jaem Club. Their internal studio first concentrated on licensed titles, but in early 1993, all game development was outsourced to Open.
In 1993, Daou made a contract with the North American Innovation, the software publishing division of The Ultimate Games Club, which in the end never released anything2. The deal extended to a whole 10 games, mentioned were Dooly the Dinosaur, Janggun-eui Adeul, Open's Wonder Kid, Koko Adventure and Toto World 3. All games were supposed to be made "suitable" to American tastes.
Daou Infosys can be confirmed to have been closed down in 1998, but Jaem Jaem club seems to have ended around 1994, as there have been no more games released under the label afterwards, and another part of the company took charge of game publishing until December 1996, when they gave up the game business altogether. The official public company history doesn't mention the branch at all, anymore.
