Never mind. I figured out my error.

Where I wrote:

NewYUSLoad
   DEX
   LDY count,X
   STX CountSet
   STY CountYHold
   JMP LeftRight

I should have written:

NewYUSLoad
   DEX
   LDY #1
   STX CountSet
   STY CountYHold
   JMP LeftRight

Thanks,

Aaron

I've been working on a vertically scrolling playfield. It scrolls fine going down. And it scrolls fine going up too, except for when it reaches the very end of the playing field where it just quickly jumps to the end. Can anyone tell me why? I'm using the Stella emulator to test it. The scroll is controlled by the up/down of the left joystick..

Thanks,

Aaron
