About using iPad and iPhone 4 retina and HD

[Dark Schneider]

Hello, I'd like to know about this, something like a fast tutorial. How it works exactly?.

In example, for a project in landscape mode, we set 1024x768, then at begin we do GETSCREENSIZE?. What coordinates report MOUSESTATE?, and for drawing, we need to set the appropiated (x,y) scaled values?, we need to load the correct media or we must use the method of "@2x"?.

Thanks.
