Hello fmoraes,

fnrc> priority 0 and background priority 0?

backdrop -> obj -> bg (highest)

Really? I don't think so.

Backdrop>BG 3>OBJ 3>BG 2>OBJ 2>BG 1>OBJ 1>BG 0>OBJ 0
Sprites are always on top =) (the numbers are priority numbers)
***

fnrc> 2. with alpha blending, how does it work if you have more than one
fnrc> target surface? What if the first surface is transparent?

objs blend only to the bg, not other sprites ... no, it doesnt quite
look like what you would expect ;/

***
I haven't played with it too much, but to my knowledge, any nontransparent
areas in your first surface affect the second surface. I'm not sure what
happens if the second surface is transparent...
