SM64 - Mario Wings to the Sky - Coinless

I collect the star Mario Wings to the Sky without collecting any coins. This video has been sped up at certain parts to minimize repetitive actions for your viewing pleasure. Note that I have a cheat code activated during the video, which shows how many objects are loaded at each moment. This cheat code doesn't alter the gameplay; it is just to assist me in cloning objects, especially when I'm doing the hat in hand glitch and can't even see what I'm cloning. Feel free to watch it to gain a sense of what objects are loading / unloading and when. And if it ever looks like I'm standing around not doing anything, it's probably because I'm waiting for some object to load or unload, so you can watch the OBJ counter to look for the change. Also, some objects activate a null bug (NULLBG) when they load, which you will see in the bottom right corner. This is because they initially spawn at the center of the course, which happens to be out of bounds in Bob-omb Battlefield.

I originally thought of trying to do this back when I did the A Button Challenge for Shoot to the Island in the Sky. But after a bit, I just gave up on it, thinking it was impossible. Later, Gaehne D. commented on one my videos [   • SM64 - Find the 8 Red Coins - 0x A Pr...  ], specifically asking me to go for it. This inspired me to try it again. And after a lot of testing and brainstorming, I ultimately devised this strategy. So thanks Gaehne D. for motivating me to go for it again! This strategy makes use of several glitches, listed at the bottom of this description. It was actually really fun to have to use so many, which is also a testament to the difficulty and complexity of pulling this off. I especially love when Mario is holding a clone, hands free, with his hat in his hand -- that's 3 glitches at the same time!

The core dilemma to collecting this star coinless is that it's nearly impossible to collect each secret without also collecting the coins around it. For each secret, there is a ring of 8 coins around it and a singleton coin practically inside of it. The hitbox of the secret is mostly contained within the hitbox of the singleton coin. But a tiny portion of the secret's hitbox extends above the singleton coin. This is why the secrets can be collected coinless in the star Pyramid Puzzle in Shifting Sand Land. However, for the secrets in Bob-omb Battlefield, this tiny portion of the hitbox is contained within the hitbox of the top coin of the coin ring. In other words, the middle and top coins of the ring entirely contain the hitbox of the secret. Here is a video to demonstrate:    • Secret and Coin Hitboxes  . So how do I collect the secrets without collecting the coins? Why, I move the coins out of the way! Note that the secret and middle coins are loaded always, and so they cannot be cloned and moved elsewhere. Only the top coin can be cloned and moved, allowing for a narrow space to collect the secret coinless! Interestingly, over 90% of the video is dedicated to just the 5th secret, since it requires advanced techniques to reach it.

I actually came up with the idea for a clone centipede back when I was doing the A Button Challenge, but there was never a practical use for it. In general, a clone centipede is when you release an initial clone, then iteratively release clones by being knocked back by the previous clone. In this way, there is always exactly one active clone at a time. Using this method, you can make a clone somewhere where you initially couldn't, and can then use this last clone for a greater purpose.
