Zelda no Densetsu - Mujura no Kamen (Japan) ROM

Legend of Zelda Majora's Mask is about Link as he ventures away from the land which made him famous (Play LoZ: Ocarina of Time if you somehow haven't already) and into a mysterious parallel universe, where a small imp by the name of "Skull Kid" found a mask with great evil power, and is going to use it to destroy Termina! Go forth (and back) in time, finding mysterious masks, each with it's own unique power, while still getting that classic Zelda feel! In my opinion, this game is HIGHLY underrated, and is really a great game! That actually means a lot coming from a Zelda-pro (both in history, and speed-runs). But my onpnion doesn't matter to you. Who cares. Go have fun with one of the best games of Y2K!
