how come this doesn't work? I set the display for the bottom screen, and set a sprite just how I would on the top screen, but it said out of range. Did i do something wrong?

specify number of sprites in upper screen, the difference is the number of sprites you can use in lower screen starting in 0, is possible use same sprite number in different screensbut not exceed the limits

You specify the number of sprites using xscreen

Wait so you can have SPSET 0 on top screen, and SPSET 0 on bottom? Is it because you have DISPLAY 1, then DISPLAY 0 just below it?

Ok I figured it out! Thanks! when I used xscreen, I told it to make the number of sprites on the top screen 512, then I noticed that I can have up to 512 sprites on both screens combined. I thought you could have 512 on the top screen, and 512 on the bottom screen.

@Aaron Yes, you can have sprite 0 on both the top screen and the bottom screen.
