Really_Tall | Super Mario 64 DS - Sign Clipping @Really_Tall | Uploaded 7 years ago | Updated 5 minutes ago
This glitch makes it possible to get Out of Bounds by reading a sign. Sadly there is only one place I know of that this works, which is the sign near the top of Wet-Dry World, as the glitch is dependent on course geometry.
The reason this glitch works is because when you read a sign, you are forced to move in front of it. During this movement there is no collision detection, and your Y coordinate is locked. You don't necessarily have to read the sign while at its height though, and with (probably) every sign in the game you can land on it, slide off, and then read it while at the height you would be while standing on it, floating in the air during all text boxes. The more interesting thing though is reading a sign while lower than it, or more specifically lower than the height of the ground you are moved to when reading it.
SM64DS has some snapping when very slightly above or below the ground. Otherwise it would be possible to fall below the ground when reading a sign on even the slightest slope. This means that sign clipping requires either a gap next to the sign, or a fairly steep slope.
The sign nearest the cannon in Snowman's Land is almost usable for this glitch, as it is on a slope. When snapped you move upwards a maximum of around 210,000 units, meaning that if you are over 210,000 units below the ground you will not be snapped, and fall below. In SL I could get less than 2,000 units away from being able to fall OoB, tantalisingly close. Getting OoB there would mean you could just jump into the cannon without talking to the bob-omb to open it, which would have the possibility of being faster for the TAS, but sadly it seems to be impossible.
One more important detail is that the address that controls your Y coordinate when reading a sign is always 2 frames (1 change) behind your regular Y coordinate. This means if you read the sign while moving up a slope, you can read it from a slightly lower position. Even with this I wasn't able to get OoB in SL though: there is a maximum speed at which you can read a sign, and you would need to find a way to read a sign while travelling faster than this to be able to get OoB.
I know this video features WDW, but as this SL strat doesn't work I have nowhere else to put this info.
To do this in WDW, first get to the top next to the sign. Performing this on the highest water level is fastest, but most difficult as you have to land on the seam of the course. At a lower level you can just fall into the water after the clip, then swim to the loading point. However, as the jump after reading the sign is pretty precise, the trick is likely TAS-only regardless.
Jump towards the sign, and also towards the edge of the platform, in such as way so that you slide off. This results in you being in a landing state, while falling off the ledge. This means that it is still possible to read the sign, as usually you can't read a sign in mid-air. Now press a direction, and 2 frames (at 60fps) later press A or B. You will now walk through the wall to read the sign. The height I read it at is the lowest possible, as the area you can read the sign is limited vertically as well as laterally. After reading it, do the smallest possible jump on the last frame where you are able to jump, after turning towards the wall. The jump here is definitely possible as Yoshi and Luigi, and should be possible with Mario or Wario at a lower water level by doing a kick to land in the water.
At the highest water level with Luigi or Yoshi you will now have to land on the seam, then jump down towards the loading point. When the town is loaded you can instantly start swimming if you are high enough. The loading point is in the middle of the pipe.
On any other water level just land in the water and then swim to the loading point.
From here just swim to the Quick Race Through Downtown! star by going around the town as I do, or over it, which may be slightly faster.
Using sign clipping should hopefully be faster than the block clip technique that can also be used to get OoB in WDW. Sign clipping is used nowhere else, while block clipping is used multiple times in HMC, so it would be cool if it featured in the 150 Star TAS!
