Punch-Out!! (Wii) - Don Flamenco (Contender Mode) in 17.74 (Tied World Record)
I do not own the rights for the audio or the game footage in this video, all rights preserved by Nintendo.
Don Flamenco is a very interesting IL due to how the timer works. If you miss 3-4 first frame hits by 1 or 2 frames each (but still hits him) you do not lose 3-4 frames. Instead you lose several seconds. The final star punch also has to be delayed by a frame, which saves about a second on the in game timer. Why? No idea.
There are speedruns for most of the games launched outside of japan, visit Speed Runs Live or Speed Demos Archive to find speedruns for the games you wish to see! The general idea of a speedrun is to complete a game from beginning to the end as fast as you possibly can.
