Unknown compression algorithm, so no useful extraction.

Encrypted with XXTea

Code:

      v10 = (cocos2d::FileUtils *)cocos2d::FileStorage::setXXTEAKey(v9, "27efb289-bc7f-3636-ae74-e747b1bea17c", 36);
      v21 = (unsigned __int8 *)cocos2d::FileStorage::getXXTEAKey(v20);
      v22 = cocos2d::FileStorage::getXXTEAKeyLen(*(cocos2d::FileStorage **)(v6   32));
      v23 = xxtea_decrypt((unsigned __int8 *)v19, v18, v21, v22, (unsigned int *)&destLen);

xxtea uses a key composed by 4 integers of 32bit (16 bytes in total), if you have the final key may be possible to put it in a script on the fly.

Here source's. Works fine. Maybe make additional encryption algorithm for QuickBMS - something like cocos_crypt ?
