"Snakes Revenge" was not done with the knowledge of Kojima and on an interview (i will try to find it later) he asks for the fans of the series to just ignore this game and says that the game is a shame
The sequel of the Original MSX2 "Metal Gear" is called "Metal Gear 2: Solid Snake"
*I think I had already posted this in another thread
*The original Metal Gear for NES is a bad port, even the final boss is not the same
*MSX was not a SONY machine. This computer was created by ASCII Corporation. Sony was just one of the manufacturers producing models of MSX (precisely the model I had at the time, a MSX2+ called "hitbit")
