FrostyZako | [Segmented] Ztar Attack - Star 172 (Pre-set HOLP) @FrostyZako | Uploaded December 2017 | Updated October 2024, 11 hours ago.
Huge thanks to sm64expert for finding all methods needed to make this star possible!

Note: Savestates were used.

For this, you need to first set the HOLP (Held object's last position) to these coordinates:

X=-12839.89
Y=4591.96
Z=-4111.30

You wanna do this in course 10. I didn't include this for this video because it is very difficult to do, instead I manually set the HOLP to these coordinates using STROOP. I don't exactly know how lenient the coordinates are but you definitely need to be VERY close to those.

After you set the HOLP you need to go to Valley of Dreams (the wing cap stage), there you need to press the switch to activate the wing cap, then you need to perform the hat in hand glitch, for that you go the wing cap box that I went to and have the second wing cap hit Mario while the animation of collecting the first one is happening.

Next you need to go to a bob-omb and grab it, make sure to face the direction that I faced when releasing the bob-omb, facing this direction is very easy due to parallel lakitu camera. You also have to release the bob-omb while the fuse timer is at an odd number, not an even, so since you cannot know the fuse timer without tools you will have a 50% chance of it working.

Next you need to enter the cave, the bob-omb will be there now, grab it as soon as it is about to explode and you will be pushed into the warp, simply warp back and hold forward, as soon as you hit the ground you need to press Z to avoid warping back (if you fail just warp back once more and try again).

Go onto the hill and make sure to manage your speed correctly to avoid clipping through the hill too early to die to the quicksand. While being at the part of the hill that I have been at you can jump and groundpound to eventually clip through the level border and fall into the wall down below, you should now be in the actual area of the level! Note that it can happen that after hitting the wall you will be pushed into the wrong direction and die, it should not happen too often though.

At last simply press B to make the bob-omb you stored become held normally again and throw it away, then you can finish the level just normally.
