s_BaseResScaleWithSD means your resource true Resolution with sd Resolution. iphone4 is 2.0f and 3gs is 1.0f and so on.
so if your DesignResolution is 480*320, and you only have retina resources, you can just set this value to 2.0f.
you can also use like this:
CCScaleSprite* spr = new CCScaleSprite(trueScaleOfTheRes);
spr->initxxxx() // like the normal sprite;
