BootlegGames Wiki

Open Corp. was a company based in South Korea that was founded by a team of ex-employees from Zemina led by Koo Eun-joong. They produced unlicensed NES/Famicom and Sega Master System games during the 1990s, and were published by Daou Infosys from 1993 onward. (Daou games made before that time were developed in-house) Unusually, they did end up making one officially licensed game; the Game Gear port of Bubble Bobble released in 1994. Open seemingly vanished during the 64-bit era of gaming, but some internal programmers remained in the video game industry and later worked for Unico Electronics Co., Ltd.
