The "$" prefix just means that the number is in hexadecimal. That's the symbol that assembly language compilers usually use, but it's the same as the prefix "0x" or the suffix "h" (i.e. $3F, 0x3F, and 3Fh all mean 63 in decimal). They're just different conventions.

If you need the animation to pause for a fraction of a second, you can insert an empty loop. I think the best place to do this will probably be either before or after "play default sound effect" command at D0/063B. An empty loop consists of four bytes, 89 xx 1F 8A, where xx is the number of frames to wait. There is an example of this in the GP Rain script at D0/65DB. There's another way to add a pre-animation delay, but it's a little more complicated so try this first. You also might need to change 1F to 0F.

I think the flickering might be coming from the command "increment frame offset every 4 loops (0..2)". Try changing the third byte from 02 to 01 (at D0/0641). That's kind of a sloppy way to fix it but it might work.
