This is a TAS of Super Mario World 2: Yoshi's Island using the newly discovered warp glitch that requires Left+Right. It improves upon Spezzafer's last any% run by 333,741 frames, or 1:32:42.35. However, because this glitch is so severe and the tas skips a lot of action, we are asking that this tas not replace Spezzafer's but instead be placed in a new glitch category, at least until the 100% run of this game is finished.
The warp glitch takes 3 different forms, all of which are performed at the world map.
1) Left+Right - determined by the # of coins you collected
2) Right, then Left+Right - determined by the # of red coins you collected
3) Right, then Left, then Left+Right - inconclusive, but surmised to be determined by the last pipe you entered.
So in order to warp to 6-8, we had to collect exactly 68 coins. There were a number of routes we considered, but eventually we settled on intro -> 2-3 -> 6-8 because of the large number of coins in the beginning of 2-3 and a hole that allowed us to die and leave the level without having to lose baby Mario. Other minor improvements came from utilizing a new acceleration method in which we press Left once, then Right 4 times, then Left, then Right 3 times, then Left, then Right 3 times, then Left, then Right 3 times, then Left, then Right 2 times, then Left, then Right for the remainder.
People we need to thank
Spezzafer - for being a god at this game and his runs showed us a lot of tricks and entertainment options
Y0SH1 - for bringing to our attention the warp glitch
HHS - for telling us the minimum condition to warp to 6-8 as well as making a test run that we could compare to
L. Spiro - for his memory watcher which helped in maintaining top speed
Nitsuja - for his great work on snes9x rerecording

adelikat: Accepting for publication along side the current published run. Though I reccomend the current published run to be eventually obsoleted by a 100% run.
