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

Miscellaneous Information

- Uses the record reset version of Snes9x (1.43v10) but can also work on v9
- Uses Super Mario World 2 - Yoshi's Island (U) (V1.0) [!].smc
- Uses death as a shortcut
- Abuses programming errors
- Manipulates luck
- Aims for fastest time
- Allows Left+Right / Up+Down
- Uses WIP1 timing
Enjoy the run.

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.

i didnt say it wasnt interesting, just not worth publishing. it didnt entertain me nearly as much as a full run would. also, some glitched runs are more interesting than others, like super metroid.

I'm giving this a yes because the concept (and execution) was entertaining (although the long part in 6-8 wasn't so interesting...). I think this is worth publishing, but I agree that it should not obsolete the other run already published; there's just too much of the game skipped here for there to be any comparison.

Don't worry, the no-warp any% will indeed be rendered fully redundant after 100% is done (all the same levels done with lots more action + more levels done in this fashion), but until then, of course…

That, that... Didn't make much sence although the submission does help somewhat. It has the same nostalgic value much like the 3 min ALttP run so it should be published mainly becuase of that.

It's a glitch, when you press left+right the game goes down instead (due to the tables for left/right and up/down being adjacent), and when it doesn't find anything there it continues going down until it lands at the RAM address for the number of coins which it then uses as the level number. The reason that holding right or left before you press left+right causes a different warp is that it starts going in the direction that you began pressing at that frame, but then continues using all the buttons that are currently pressed to determine the direction when it doesn't find anything. I've checked all possible level values, and there are none above 68 that put you in an usable location.
That's pretty slick, but what happens when you do the glitch when you have say 70 coins, or 80 coins? Does it just crash, go to some random location in memory or what? And if it does go to a location, is it always the same location, and are there differences between different non-level locations (like 70 vs. 80 for example)? I know this isn't exactly on topic, but it just struck me as interesting when I read this.

70 coins brings you to a deloaded level where you die falling immediately. 80 coins brings you to 1-1. There are also some other weird levels you can go to, but none of them are useful.

Vote: Did you like watching this movie? (Vote after watching!)
I think some of us are forgetting what it says up there. Everyone's entitled to their own opinion, though. I thought it was okay-ish. It is a great demonstration of the glitch, but I guess I've been spoiled by the full run of the game. Still, I enjoyed it for what it was and even brought on the popcorn. Don't count this as an obsoletion of the one already up here, though. The full run is a whole lot more entertaining.

I found this to be very entertaining. A clear yes-vote. Even though this has already been published it is well deserved of another vote in the right direction. :)

i vote no, more then the first quarter needs to be interesting and in this movie, only the first quarter was good. the rest just dragged on and was only interesting because i never beated the game, this does not make it good enough to vote yes tho.

I was thinking about something... People are saying it's impossible to try this on a console because you can't push left and right at the same time, but what if this works on the GBA version too? If you played it via Gameboy Player and used the Gamecube controller, couldn't you push the analog stick one way and the d-pad the other? This same principle could apply with Wii's Virtual Console and the classic controller. Trying it with, say, Link to the Past (since Yoshi's Island isn't on VC yet).

Could be, but keep in mind that the up+down trick in link to the past needs to be pretty acurate to trigger the glitch.

Glitches got removed with each new version. So I doubt such a glitch is possible on GBA or VC.
