I found a mod on the forums that allows different kinds of monsters to be spawned (other than the norm), with certain 'boss' type monsters. Sure, most of them won't look like the monsters or bosses that Zelda had to offer, but it's the best I can do.
So far I have the Spirit Temple started, but it's far from complete. My ultimate goal is to recreate every dungeon from Ocarina of Time, and a few from Link to the Past, as well as one from Twilight Princess. What these dungeons are...is a seeeeeecret.
If that matters at all.
Anyway, I just thought I'd throw this out there. I'll be updating this regularly with some of the new/finished dungeons. Thanks!
