The Three Dragon Story

This game is a re-convertion from SG-1000 version of Three Dragon Story, an old console from SEGA. This game was made in Korea for MSX, and later ported to SG-1000. The original name is "용의 전설".

The Three Dragon Story is an unlicensed shoot-'em-up that is noticeably inspired by Konami's Knightmare and even improves upon it in several aspects, such as adding a health bar and a proper weapons system.

It is also known for being very difficult and punishing, even having design features that would not look out of place in a bullet hell game (years before the term itself was even coined).
