As I made a game using cocos2dx for android.
And successfully ported that game in ios also.
Now I am trying to port that game in Windows Phone 8.
Problem 1 : There is no class files for CCBReader in cocos2dx-0.13.0-wp8-0.8, hence we can not load CCBI file in windows phone 8.
Problem 2 : As I used cocos2dx, I used method which are not deprecated like eg. CCScene::create(), But in wp8 library there are deprecated methods CCScene::node. Hence I have to change for all earlier methods which were used in cocos2d deprecated in cocos2dx.
