Thanks - but I am not sure how to actually make those adjustments.
I saw in the appdelegate that there is the :
It looks like just before that I should be able to use the
cocost2dSetup setObject: forKey:CC________]
but I realize I have actually no idea how to use that thing. 8-O
The other thing, which I think is actually causing my trouble is that if I make a new SpriteBuilder project, and then just run it from XCode, I get a file not found error on the configCocos2d.plist file in the output log. That file is present, and in the Resources-->Published-iOS director (when viewed in XCode). If I click on it, I can see that it has the screen setting as selected from Spritebuilder.
Ok - so just for fun (and since it was within my ability), I dragged the configCocos2d.plist file from the Published-iOS directory into the Source folder and told it to make a copy. I then ran it, and all the little sprites were in the correct place on the iPad simulator.
Possibly a bug?
