I just started Mario 74, that's what brought me to this site.

Are there any good challenging fan hacks for any of: Link to the Past, Super Metroid, or Donkey Kong Country 2?

LTTP was my favorite game growing up and I regret terribly that I used guides the first time (I was 9 and stupid!) So I'd really love to play that same game with a fresh set of challenging dungeons. And I think Super Metroid and DKC2 are two games that lend themselves perfectly to challenge hacks because they're games that contain a lot of weird things you can do to get to weird places, Super Metroid with its wall jumping and power jump and DKC2 with throwing your buddy around, Dixie gliding, and all the different animals.
