    The bolded number is what governs the frames of the animation. I changed it to 4 in my own ROM, and it skipped frame number 5. I put 6, and there was an extra blank frame added between 5 and 1. This is useful for my hack, as I made a flower animation that has only 4 frames.
    Yes, r1 seems to be the number of frames.
    But look the other animations, it gets some operations involving r1.
    I do not debug that part out of laziness, I do not know the values that it receives after these operations.
