Does transparency with BG not work or something? I've got the dark area on this box set with BGCOLOR 1,RGB(0,255,255,255) [Yes it's on layer 1] and it still shows up completely... Anyone know what to do?

Try making the zero a one and see what happen's.(I'm just guessing)

BGCOLOR 1 isn't transparent but BGCOLOR 0 is

Alpha value of RGB() is invalid on BG. Let's fill the dark area with zeroth BG tile.

Alpha rules on the BG is the same as GRP: certain setting make it invisible, and others make it opaque. No inbetweens, unfortunately.

Ok, thanks everyone! Also, I DID notice sprites can easily be made transparent. I'll try making the box a sprite instead.
