Whoa! I thought I was done playing the PunchOut!! series, but they pull me back in... PunchOut!! The Master Edition includes every single PunchOut!! opponent in the entire series, except Donkey Kong and Doc Louis from the Wii version. All put into the original engine. This thing is awesome. You can also choose from different version of Lil Mac, I chose the version that stacks stars like the Wii, and turns out it makes the game way harder lol. It has no real ending, and you can fight any opponent at any time. This, to me, is the definitive version of the classic.
