BGSCREEN fails on layer 2 and 3

Perhaps I'm doing something wrong, but BGSCREEN seems to break for me on layers 2 and 3

BGSCREEN 0, 64, 64 'works
BGSCREEN 1, 64, 64 'works
BGSCREEN 2, 64, 64 'doesn't work
BGSCREEN 3, 64, 64 'doesn't work

Anyone else have this problem? This is in a program BTW, not the command line interface.

Nevermind, I figured it out. Had to put

XSCREEN 3, 512, 4

The 4 is key there.

The 4 is how many layers you want?

Yes that's correct.

Try BGSCREEN 0,888888, 888888

Unfriendly and obnoxious is discouraged. This crashes your 3DS. Not just SmileBasic, the 3DS system.

So it powers it down?
