Can I not load maps with XSCREEN 2? If I were to do XSCREEN 0, then the map loads just fine! Please help me! It gives me the error "Out of range in BGSCREEN 0:6"

Forgot to add screenshot...

It should be XSCREEN 2,128,4 I think it should work.

The 128 in the Xscreen is the sprite assignment, which is basically how many sprites you want on the top screen, and the 4 is the BG assignment which I believe is the amount of BG layers you want.

Interestingly, the bottom screen takes the leftover sprites (512-# on top screen) and background layers (4-# on top screen). For example, if you did "XSCREEN 3,512,3", the top screen will get 512 sprites and 3 background layers, as usual. However, the bottom screen receives only 0 sprites and 1 background layer! If you use "XSCREEN 3,0,0", then the bottom screen will get all 512 sprites and 4 bg.
