While Dracula X does have a lot of animation, a high number of frames isn't the only thing needed to make "good animation". The biggest letdown in that game is Rhicter himself, who is a pretty horribly drawn sprite, as were all CV game main characters up until that point. They walk like they've been holding a huge shit for the last 6 hours. Its kind of depressing really, since almost every other thing in the game is amazingly good.
A side note: regarding the SNES's 64/128kb VRAM limit. I think there was some way around that, and I think Doom used it. Yeah, Doom. Kind of a waste. Maybe they added VRAM to the cart, perhaps? I don't know. I remember reading something about it when the game was new.
Am I missing something? Is there something special in Magical PoP'n that I didn't see?
From a technical perspective the number of frames and sprite sizes are probably the same or less than PCE/MD, but the end product is pretty slick thanks to the artists. You'd probably have to be non-autistic to see it though since it has nothing to do with RAM, sprite size, who made the machine, etc.
