CameraSpeedCurve

{63}

This instruction writes a value to 0x80166054; a value which is read every time a Camera instruction starts. Seems to affect the camera's acceleration; {63}(rC9) will cause it to accelerate at the start of the movement, and decelerate towards the end. See https://youtu.be/APidxwgtGSk for an example of this.

The first digit of the value seems to adjust the strength of the acceleration. At 0X, the acceleration is unnoticeable. At FX, the acceleration is at its most noticeable.

The second digit seems to affect how the acceleration works. There only seem to be three categories of acceleration, based on testing in the FX range:

No acceleration X0, X4, X5, X6, X7, X8, XC Accelerate immediately? X1, X9, XD Accelerate after a slight delay? X2, X3, XA, XB, XE, XF
