"Average emulation with improved music"
I still prefer the original Super Castlevania 4 music. Game boy games are still fun to play especially in black and white. Some areas remake music shine and for nostalgia you can play it hours.
My only concern is the emulation which I felt not tasking up to the mark..motion or moment seems bit slow compare to Snes in Super Castlevania 4. Anyway I'm waiting for Symphony of the night, I still have my Psone unfortunately never got it played.
