For the DSi version of the game (anniversary edition) there are 2 extra levels (realm of memories and hero's trial), you can technically then 100% the game by beating both of these and getting all hero's keys (getting 5000+ rupees in each main level) and completing all door's in Vaati's palace. It might revive this otherwise dead game! Thanks!!

The problem is that nobody (that i know of) has sunk the time required to get 100% casually yet and it is fairly hard to blind speedrun a game. But i bet that if you do an 100% run and put it on the discord you could get it submitted in a new 100% category, but that is not for me to decide.

Hi, we've had a chat about this, and we'd be open to creating a leaderboard for the described run if someone was to perform it, as qazy suggests.

Hmm.......currently, I'm doing casual runs for the entire Zelda series, but I had a lot of fun with Four Swords. Definitely underrated. After I'm all done, I'll give this hypothetical run a try. Be warned, though; my casual run of BotW will be totally blind, so don't expect anything from me for a while.
