Clover

Clover (크로바소프트) founded in 1983 was a South-Korean company, known for publishing unlicensed software for the MSX and SEGA systems. They typically modified the games to remove the original copyrights. They did publish a few locally developed titles, but even those were typically based on Western or Japanese titles. In 1987 a copyright law was enacted to curb this wide spread practise.
