Hi Thomas,
I have taken yours and Andrews suggestions and I'm gradually moving them in. I'm also trying to do a little detective work based on the suggestions given.

I found time to play with these routines and I have a few questions. Some I'm sure will benefit others in their conversion process.
> Example:

Would playerMotion here be the "delay" frames I have set up for the players (i.e. 4, 3, 2, and 1)?

you clear the carry bit instead of setting it so a bcc would move the player for the given frame.
Wouldn't this work for only 2 frames? I think I'm missing it here. I say that because I worked it out once before and it seemed to work :confused:
$04 - $3F = $C5 -> carry set, right?
$C5 - $3F = $86 -> carry cleared???

The below routine works perfectly! I like it better. Probably because I understand it better :) My only question for this is where do you come up with the number 30? I understand you get 36 from 30*6/5.

As a matter of fact, where did you get the numbers for the first routine? Is there a formula you're using that I'm missing?
Again, thanks for your time. It is *greatly* appreciated!
Take care,
Dennis
