This is rather interesting! Bubble Bobble was one of my all time favorite. Totally reminds me back in the days, where my family owns a 1986 IBM 8086 AT machine with 20MHz, I think it's pretty awesome that time, with a greyscale monitor that only has black and white, playing with the original Bubble Bobble on a floppy disk which only have 360KB capacity! I have the original episode here with my NES emulator, but decided to go with BB2 first since I love the graphic so much.
