Set resolution of Cocos2d-x ver.1


Hi All,
I use Cocos2d-x ver.1, I don’t know how to set the resolution to 960 x 640. I just can enable retina setting, the picture is in 960 x 480 but the coordinate is 480 x 320.
In Cocos2d-x ver. 2, got “setDesignResolutionSize”, but not in ver.1.
I use ver. 1 because Cocos2d-x for WP is ver.1. It is easy for me to just copy from WP code to iOS or Android version without massive changing the code.(Code 1 time for 3 platform)
Do anyone got solution, otherwise I have to code by using ver.2 for iOS and ver.1 for WP.
Thank you.
