that's chronological chart of main-line Bubble Bobble games with all available subtitles and their inconsistencies.
so, we got three OFFICIAL Bubble Bobble 2, and two OFFICIAL Bubble Bobble 3.
should i add rumoured subtitles like that? :
[Lord_Nigh] whats really weird is i saw a new zealand story japan machine at a doctor's office 20 years ago, and it said "the story of bubble bobble IV" or something on it
