Bubble Bobble is one of my favorites game ever, and the version i grew up with and played the most was the c64 version by Ste Ruddy. But there are many conversions of Bubble Bobble for different systems. I did this image just for fun to see the how Bub and Bob sprites look on different conversions.
Here is a list of all the different Bubble Bobble conversions: http://strategywiki.org/wiki/Bubble_Bobble/Ports
And if you want to play Bubble Bobble in the best way you can but dont have the original Arcade cabinett at home it is said that the Sharp x6800 and Master System version is the best conversions of the game.
