Ten years is just the beginning, because even now new games fall into our hands from time to time! Of course, the best games have long been known, but no one will refuse to try a new, even mediocre game. Here's The Dinosaur Dooley for the Sega Master System (Agigongnyong Dooly), a strange unlicensed Korean side-by-side shooter starring an unknown dinosaur and a cheap soundtrack based on Nirvana's Smells Like Teen Spirit! Credited "(C) DAOU INFOSYS 1991" and "(C) INNOVATION TECHNOLOGY 1993". The game was mentioned in several magazines, along with other products from Innovation, however, it did not appear in the US. What is the duration of the game? Who knows? I didn't have the patience to even get to level 2.
The game is based on Korean cartoon series. Two versions of the game are known - the Korean original, which has Korean characters on the inlay, and the Western version (which was also sold in Korea), from Innovation, in which the inscription "The Dinosaur Dooly" looked right.
