   I'm just updating my game to run with retina display, i've managed to borrow and iPhone 4 for a day to test it and have fallen short at the first hurdle!

   RMPlayerSprite *player = [RMPlayerSprite spriteWithFile:@"playerBlue.png" rect:CGRectMake(0,0,50,60)];
   	[player setDelegate:self];
   	[player setScaleX:-1];
   	[self addChild:player z:50 tag:kPlayerSprite];

   This crashes the app, at line addChild:

   I'm getting the SIGABRT and

   NSAssert( child != nil, @"Argument must be non-nil");

   I think what is happening is because there is no playerBlue-hd.png it is failing, I thought that if the HD graphic wasn't present, it fell back onto the previous one?

   Only 70% of my game has HD retina graphics at the moment, is there a fix, or something I am doing wrong?

   Thanks

   EDIT:

   2010-12-06 10:40:31.388 Game_CC0.99.5[745:307] cocos2d: CCTexture2D. Can't create Texture. UIImage is nil

   2010-12-06 10:40:31.396 Game_CC0.99.5[745:307] cocos2d: CCFileUtils: Warning HD file not found: leftNavItems-hd.png

   I've noticed that this logs out about 20 times previous to the player sprite.

   If I turn off retina display, this works 100%, the leftNavItems.png file is definitely there.

   By-the-by, did you realise you can test the retina display in the Simulator? Change the hardware type in the simulator and then hit "Run" in Xcode and it'll run in the chosen hardware type. (Not the iPad hardware types though, Xcode uses a different Simulator profile for 'em)

   There's been some changes in the image-loading routines since 0.99.5-rc0. What version of cocos2d-iphone are you using?

   Can't seem to workout what i'm doing wrong, the demo's don't crash, and i've not set anything differently to them, i just created a cocos2d+box2d template project using the install-templates.sh...
