SKOB, aka Shuangchuan Trade Corporation (上川貿易有限公司), is a Taiwanese publisher of Mega Drive and Game Boy games. SKOB published both original games and (on the Mega Drive) unofficial Chinese translations of Japanese games.
SKOB appears to be connected to a Chinese company called "Super Huge Dragon" aka "Guangzhou Mega-Dragon Electronic (Software) Trade Center" which has an identical dragon logo to the one sometimes used by SKOB, and appears to have released at least four SKOB games in China.
