On an overclocked sandy bridge or greater system, virtually any wii game, PS2, playstation, SNES, etc. game can be played and with the original controller and USB adapter. You just have to make sure you have a paid for copy of the original game to keep things legal.
I for love what the Wii games look like on an overclocked system. I have original N64 and PS2 controllers and recently bought an Xbox 360 wired controller... for Witcher 3.
I love the "parallel worlds" remake of link to the past... I've played through that one multiple times... it's satisfying getting the cane of byrna and magic upgrades to become a walking God by the end of the game. It's a very hard game until you figure out how to break it.. even the first dungeon really isn't THAT hard if you pick up the 4th heart container in the church. I play version 1.1
