I had a simple app created previously running on Windows8 RP. For the app to be submitted, we were requested by Microsoft to build our project on MVSE 2012 for Windows 8 RTM version.
Upon doing do, it was discovered that CCSprite is creating null sprites. After some tracing, I found that the CCFileData call within CCTextureCache::addImage function failed to load the image file’s data despite the image file is already within project resource.
