I was working on wp8 version, I use this code from demo. also my images designed base on 480X800.
CCEGLView* mainView = new (buff) CCEGLView();
CCLOG ("Device Res:%d", m_deviceResolutionInPixels);
mainView~~>setDesignResolution(768, 1280); // already changed this to mainView->setDesignResolution(480, 800); still wrong.
it work well on DeviceResolutionInPixels_WVGA mode(phone screen resolution is 480X800), but on DeviceResolutionInPixels_WXGA(phone screen resolution is 768X1280) mode, sprites is not be scaled properly, all sprites still in 480X800 size.
I do not know what is right way to support Multi resolution in wp8 version.
Any help is appreciated. Thanks.
