Right now im trying to figure out why my scrolling field doesnt include the entire playfield? I have the pixles at 88 high, but when I use scrolling. Only the first screen scrolls over and over? not the entire playfield? 2, without a multikernel sprite option. How can i make my playfield a little more detailed? I tried using pfcolors, but it still isnt what I want? Thanks for any help.

Unfortunately, the batari Basic vertical pfscroll doesn't work the way you're thinking it does in the standard kernel. To make it work the way you want, I think you'll need to customize the standard kernel a little bit, and you'll need to use a combination of manually changing the playfieldpos variable and the playfield starting address, with the playfield being in ROM rather than RAM. This might not be too difficult to do, so if I can find the time, I'll tinker with it to see if I can make it work that way.
