adding moar values

2021-06-09T05:30:03Z

Bomb Jump HGBFS was listed as 34.62464, but mathematically it should be 35.62464. Testing on practice rom confirms 35.62464.

2021-06-09T05:17:52Z

The math got flipped for walljump HGBFS value; it was listed at 101.58368 but it should be 100.7168.

-Note shinesparks have a cap on the pixel value of 14 (in both NTSC and PAL, in any medium). The subpixel value continues to change, following some pattern that I forgot and could not quickly find.
+Note shinesparks have a cap on the pixel value of 14 (in both NTSC and PAL, in any medium). The first frame will be 7 pixels, and all remaining will be 14 pixels. The subpixel, though, continues to accelerate with a quadratic relationship with respect to the given acceleration values in region and medium above. Thus, for example, on NTSC in air, the subpixel acceleration is:  7168, 14336, 21504, 28672... This gives subpixel veloctiy values of 7168, 21504, 43008, 6144... For most RTA purposes, this is effectively random:  Some frames will move Samus 14 pixels, and some 15 pixels.

 Crouching before jumping will cause Samus to begin her jump eight pixels higher than if she did not crouch.
+[[Moonfall]] is a glitch that underflows the fall speed, allowing you to continuously gain speed without hitting the cap. When doing a moonfall, the address used for direction has a value of 0.
