The master system version of the game is decently different, with lack of continues, slightly different enemy arrangements, bosses having MUCH less health, and an entire extra level with a unique medusa boss in the middle of the game.

Wouldn't it be better to separate out the Arcade release (August of 1987) and the Master System release (January of 1988) into different game pages?

Since its still the same game even with differences it stays under the same. We did the same with Wonder Boy the first one. It would be only a different thing if you would submit both under the same category.

Thanks for the explanation.
