Thanks for the help.  I'm printing it out now to digest.  I actually had 
already thought of two of the things you suggested!  Well, I've impressed 
myself anyhow.  I already implemented splitting up the PF data into two 
places so that I didn't have to increment the pointer twice and it hit me 
yesterday that moving the checks to the end of the scan would help 

I had not thought of the non-indirect y-indexing.  Honestly, I don't know 
what it is, and will have to read up.  Neither had it hit me to just 
check for the player every other line since I'm moving it two scans each 
frame the joystick points up or down.  Thanks much!  This will free up a 
ton of space that I was wondering how to coax out of my code.

Ha!  ;^)  Nope, the internet didn't eat it, but it did eat your email

Is this your address?  Thanks for the code.  Let me paste in some of my

Thanks again; I've got lots of work to do!
