A few months ago, at a fest with two Sheik mains, we got into a long discussion about Sheik’s vertical turnaround up-b after one of them performed it and the other thought it was nigh-impossible. This eventually culminated in this quick video guide by Emilywaves on how to perform up-b turnaround, which was good, but lead me to realize there was no hard data on what the viable inputs for vertical up-b turnaround were. So I set about painstakingly researching the value ranges that resulted in Sheik getting a perfectly vertical reverse up-b. The results here haven’t been rigorously tested with other characters who can perform a reverse up-b, but tentative testing with a few different breakpoints/values show that they’re likely identical for Pikachu, Pichu, Zelda, and Mewtwo.

Here’s a rough pixel-by-pixel map of the 255×255 inputs for Sheik up-b. Yellow represents an (x,y) value that results in a non-turnaround, standard vertical up-b, purple represents a value that will give you a directional angle on your up-b, red represents a value that will, if facing left, give you a turn around up-b, and blue represents a value that will give you a turn around up-b if facing right.

Any value that would give you a turn-around up-b if facing the opposite direction would result in a normal vertical up-b if you’re already facing that way. Thus, if facing left, the input map would look like this:

and if facing right, it’d look like this:

While the red/blue areas were rigorously tested and I can guarantee their accuracy, do note that the yellow/purple areas have not been rigorously tested, and are somewhat simplified, as it does not differentiate between shortened and fully extended up-b’s (for example, a horizontally centered up-b with Sheik will shorten between vertical values 169 and 202, with less distance the lower the value – a higher or lower valid vertical up-b input will result in a max-height up-b). The purpose of the areas outside the up-b turnaround values is more to give the values spacial context than to serve as a holistic map of Sheik’s (or another characters) up-b.

Below is the full table of values that will result in a turnaround up-b, which were tested in Dolphin and used to illustrate the input maps above. The values given are using Melee’s input system, which range from -1 to 1 on both axes, centered at 0 and incremented by 0.0125 (80 total values for each axis).
