Was browsing Nico Video just now and came across this amusing video of a Tool Assisted Speed Run of KOF2000.Never knew anyone made these for KOF, i've only really watched Super Mario ones before.
It's technically not much of a speed run though, more of a showcase than anything else.
Some of the things shown include Kim sliding across the floor with his foot stomp, Seth doing his counter over and over again, and multiplying Baos walking in the air.
It's an interesting watch. More than anything it's funny just to see how much someone can 'break' the game.
Check it out on Nico Video directly, though you need an account, here.
Or if you don't have a Nico Video account you can copy and paste the url ( http://www.nicovideo.jp/watch/sm14521237 ) into MadMan's cafe's Nico Viewer.
