   I can't get pvr textures working with sprite frames and pvrtc files...

   The plist that zwoptex generates references frames by 'FILENAME.png'. I run the sprite sheet png's through pvr generator so my spritesheets are pvr not png... So I end up creating my CCSpriteSheet like so:

   self.sheet = [CCSpriteSheet spriteSheetWithFile:@"SpriteSheet1.pvr" capacity:100];

   Now, when creating a CCSprite with a frame name, I use the 'Sprite.png' as an argument to 'spriteWithSpriteFrameName', it does not load. as well, is i use 'Sprite.pvr' as an argumen to 'spriteWithSpriteFrameName' is still does not work...

   Is there currently a solution to use Zwoptex frame loading with pvrtc?

   I'm assuming theres some magic behind the scenes that loads the sprite frames from the plist when you use '[CCSpriteSheet spriteSheetWithFile]'...

   1. Add the .pvr manually to the CCTextureCache.
   

   /** Returns a Texture2D object given an file image
    * If the file image was not previously loaded, it will create a new Texture2D
    *  object and it will return it.
    * Otherwise it will return a reference of a previosly loaded image.
    * Supported image extensions: .png, .bmp, .tiff, .jpeg, .pvr, .gif
    */
   -(CCTexture2D*) addImage: (NSString*) fileimage;

   2. use that texture with CCSpriteFrameCache:

   /** Adds multiple Sprite Frames from a plist file. The texture will be associated with the created sprite frames.
    */
   -(void) addSpriteFramesWithFile:(NSString*)plist texture:(CCTexture2D*)texture;

   The API Reference is your friend :)
