   Upgraded to SDK 4.2 l'm building for iPhone (Retina) simulator with cocos2d: cocos2d v0.99.5-rc0; i've called [director enableRetinaDisplay:YES] successfully but despite there being xxx-hd.png available, the cocos2d console messages seem to say that xxx.png is being looked for.

   I didn't have this issue before the SDK upgrade. This seems like an important bug but I can't find mention here. There was mention in the reported bugs but I'm not sure of the circumstances there.

   So am I alone on this?

   Everything is working on my end with 4.2, 0.99.5-rc0 and retina in the simulator, are you sure you the simulator is using the retina device and not the one that looks like an Iphone 4?

   Oh dear, sorry to hear that. Yes I have the simulator device set as "iPhone(Retina)". Where to now? I'll go back to check the bug report. It was actually your own concern that made me suspicious of the reported bug.

   More info .. i have a pair of files xxx.plist and xxx.png (for use with addSpriteFramesWithFile. xxx-hd.plist and xxx-hd.png do indeed exist and are part of the project. I look at Build Results and they are copied as part of the build. When run this code section in CCFileUtils returns 0 for both files. The pathForResource method returns nil! NB, an earlier attempt to find an earlier yyy-hd.png works fine. BTW, there is no xxx.plist or xxx.png, only the HD ones. So where to begin for this one? I've checked spellings, but there is a problem somehow, but where to look?

   `+(NSString*) fullPathFromRelativePath:(NSString*) relPath
   {
   NSAssert(relPath != nil, @"CCFileUtils: Invalid path");

   NSString *fullpath = nil;

   // only if it is not an absolute path
   if( ! [relPath isAbsolutePath] )
   {
   NSMutableArray *imagePathComponents = [NSMutableArray arrayWithArray:[relPath pathComponents]];
   NSString *file = [imagePathComponents lastObject];

   [imagePathComponents removeLastObject];
   NSString *imageDirectory = [NSString pathWithComponents:imagePathComponents];
   fullpath = [[CCConfiguration sharedConfiguration].loadingBundle pathForResource:file
   ofType:nil
   inDirectory:imageDirectory];

   }

   if (fullpath == nil)
   fullpath = relPath;

   #ifdef __IPHONE_OS_VERSION_MAX_ALLOWED
   fullpath = [self getDoubleResolutionImage:fullpath];
   #endif // __IPHONE_OS_VERSION_MAX_ALLOWED

   return fullpath;
   }

   Looking at that code, it won't find the -hd version if the non-hd version doesn't exist... That seems backwards to me, but is already being discussed in another thread on this forum, I believe...

   Anyway, if I'm right, the workaround is to create empty xxx.plist and xxx.png files, and then it'll find the xxx-hd.plist and xxx-hd.png files.

   I think http://www.cocos2d-iphone.org/forum/topic/11123 might be the same problem. I can't find the discussion I thought was going on, and if making the empty files fixes this bug for you, you probably should report it into the bug tracker.

   TBBle, thank you. Yes creating empty such files get's the show moving. I'll report the bug. Thanks again.
