Yeah, I read it (and I see you changed it shortly before or after your above reply), but it doesn't really answer my question... well, that is to say, it does and it doesn't.
An alternate way to look at it is: does an 8x16 sprite with vflip=1 have its 0,0 coordinate in the lower left corner (effectively 0,15) or does it remain at true 0,0 (upper left corner)?
EDIT: Never mind. Figured the ordeal out. vflipped 8x16 sprites result in the "2nd half" 8x8 tile being drawn first, then the "1st half" being drawn after that. E.g.
Code:
vflip=0 vflip=1
+-BB-----+ +-AA-----+
|12222221| |10101010|
|00000000| |00000000|

Note which tile gets put in what order; with vflip=1, tile AA gets drawn (pixels reversed) first, while tile BB gets drawn second. I guess if it didn't do that vertical flip with 8x16 wouldn't be very useful/logical.
