Speed values: What exactly do they represent?

[NaitorStudios]

I'm recreating SMW engine, and I've noticed that the speed values don't seem to be pixels, 20 for instance seems to be 1.25 pixels, but I'm not sure how to convert the values in the tas script into pixels...
Could you please help me with that?

Ah, I think I realize it now... Speed is multiplied by 16

The game uses pixels to represent an actual pixel unit on video.
There're also subpixels:

• $7E007B | 1 byte | Player | Player X speed (8-bit, 2-complement signed), in 1/16s of a pixel per frame.
• $7E007D | 1 byte | Player | Player Y speed (8-bit, 2-complement signed), in 1/16s of a pixel per frame:
• $7E13DA | 1 byte | Player | Accumulating fraction bits (fractions of 16; bits 4-7 used while bits 0-3 are always zero; #%XXXX0000) for fixed point player X position (not to be confused with $7E007A). This is used mainly for player's X speed position movement to enable increments for less-than a pixel.
• $7E13DC | 1 byte | Player | Accumulating fraction bits for fixed point player Y position. Same format as $7E13DA but Y position instead of
