We just published a tutorial about using CocosBuilder on Cocos2d-X
Good tutorial. I added it into [[Tutorials]] wiki page.
Thanks Walzer. I think I have found a bug in CCBReader, can you have a look at this please? http://www.cocos2d-x.org/boards/6/topics/17607
FYI I wrote a small tutorial to explain how to integrate the latest version of CocosBuilder (which generates platform-dependent resources) with cocos2d-x, to have a multiplatform project. Might be helpful: http://2sa-studio.blogspot.com/2013/04/setup-cross-platform-project-with.html
