Hi!
I'm making a sort of old school game where I wanna use a lower resolution (half) than the iPhones screen to get that really primitive look so that each pixel is 2x2 pixels.
Right now I just scale up my images twice as big in the original file and add them to my stage with the original scale in cocos2d, but it feels as a waste of memory and cpu. Also, I have to move everything by 2 pixel steps which is kind of an ugly solution.
Is there a way to change the openGL matrix/ortho or whatever it's called (im pretty new to the whole openGL thing) so it draws the stage in double scale (no smoothing!) so I maybe get some extra performance out of the iphone (since it only have to render half as many pixels as my current solution) and more logical coordinates.
Thanks in advance!
