im gonna guess that the reused models here have a higher poly count or higher quality textures. Am I right?

@Draco Rex: The Japanese version had an exclusive minigame called Navi Trackers (a.k.a "Tetra's Trackers"), which all of these models originated from.

is this right? these models are for windwaker, not four swords adventures

@Someone
I'm pretty sure the Helmaroc King, at least, is 3D

Doesn't the main game occasionally uses a few models ?

I know it's a sprite based game, but some elements seems way too elaborated to just be sprites. I notably think of Beamos eye : it's a white ball which turn around the statue, and seems to lack a shading (strange for a sprite). There are tons of positions (maybe 200, it's very very detailed, more than everything else in the game including Ganon), and it has an illusion of relief. And last but not least : it shape is updated of a few px for each move.

(Oh and also, but maybe it's just me : it seems to be nowhere in the dumped spritesheets)

There aren't any more areas, really. The rest are all sprite-based.
