Don’t know how to use the Git properly, but the bugs for #438 & #420 are fixed in my fork version.
#438 : Not being familiar with the core engine architecture, but the problem is the selector’s function name “update” cannot be used in device. I temporary fixed it by adding another function name “update2” called by the selector and it worked.
CCMotionStreak.cpp line 53
CCSprite.cpp line 119
CCSprite* CCSprite::spriteWithFile(const char *pszFileName)
CCSprite *pobSprite = new CCSprite();
Hope that helps
