I have no idea where or how, but I lost my Bubble Bobble game.  I have a habit of taking my games and systems to others' houses to play some NES, but I have never lost a game before well except that one I let my friend "borrow" and never got back.  Anyway it has probably been missing for almost a year now.  I loved Bubble Bobble as a child and I would often rent it from my local video rental store.  And luckily when the video rental store started selling their NES games I was able to buy the same Bubble Bobble I rented as a child.  But now unfortunately it is gone.  I'm hoping it will turn up someday- it drives me crazy that I lost it.

Bubble Bobble isn't too rare, is it?  And Rainbow Islands which is Bubble Bobble 2 is the more rare game of the two correct?  I found that one at the video rental store, too.

Also on a side note, I noticed they have a few Bubble Bobble games for the DS.  Is Bubble Bobble Double just like the old game and Bubble Bobble Evolution is an updated version?

Bubble Bobble Revolution has a version of the original BB game as well as a 'newage' version.
