Bust A Move Again (Puzzle Bobble 2)

I remember it in the arcade and loved it. I have Bust A Move 4 for PS1. Am I missing anything from the original Bust A Move Again?

i have
bust a move on neo
bust a move 2 (again) on saturn,
and 3 saturn, 4 dreamcast, millennium gbc,
99 n64, ultra xbox, 3000 cube, super, and super 2 on ps2..

and i gotta say b.a.m. 2 (again) is the best one of all.

i want it for mvs

I agree. Anything after Again / Again EX is just wrong, IMO. I mostly like it better because it's simpler. The later ones started adding things like moving walls and such that I just thought was overkill.
