   I'm trying to port over my code from 8.xx to 9.91 and am having an issue.

   My code is as follows:

   @implementation MainMenu
   - (id) init {
       self = [super init];
       if (self != nil) {
   
   	CCSprite *back = [CCSprite spriteWithFile:@"tiltshift.png"];
   	back.anchorPoint = CGPointZero;
   	[self addChild:back z:-5];
   
   	//[self addChild:[MenuLayer node] z:0];
   
   	}
   	return self;
   }
   
   @end
   
   @implementation MenuLayer
   - (id) init {
       self = [super init];
       if (self != nil) {
   
   		CCMenuItemImage *next = [CCMenuItemImage itemFromNormalImage:@"Icon.png"
                   selectedImage:@"Icon.png" target:self selector:@selector(nextCallback:)];
   
   		CCMenu *menu = [CCMenu menuWithItems:next, nil];
   		[self addChild: menu z:1];
   
   		next.position = ccp(115,300);
   
   		[menu alignItemsHorizontally];
   		[self addChild:menu];
   
       }
       return self;
   }
   
   -(void)nextCallback: (id)sender {
   	OneScene * one = [OneScene node];
   	//[[Director sharedDirector] replaceScene:introne];
   	[[CCDirector sharedDirector] replaceScene:
           [CCMoveInRTransition transitionWithDuration:0.5 scene:one]];
   }
   
   - (void) dealloc
   {
   	[MainMenu release];
   	[super dealloc];
   }
   
   @end

   When I add [self addChild:[MenuLayer node] z:0]; to the @implementation MainMenu the app crashes.
   Without this the menu doesn't show up. It works perfectly on the 8.xx version.

   I'll post this just in case it helps someone.

   +(id) scene {
   
   	// 'scene' is an autorelease object.
   	CCScene *scene = [CCScene node];
   
   	// 'layer' is an autorelease object.
   	MainMenu *layer = [MainMenu node];
   
   	// add layer as a child to scene
   	[scene addChild: layer];
   
   	// return the scene
   	return scene;
   }
   
   - (id) init {
       self = [super init];
       if (self != nil) {
   
   		CCMenuItemImage *next = [CCMenuItemImage itemFromNormalImage:@"right.png" selectedImage:@"left.png" target:self selector:@selector(nextCallback:)];
   		CCMenuItemImage *previous = [CCMenuItemImage itemFromNormalImage:@"left.png" selectedImage:@"right.png" target:self selector:@selector(previousCallback:)];
   		CCMenu *menu = [CCMenu menuWithItems:next, nil];
   		CCMenu *menu2 = [CCMenu menuWithItems:previous, nil];
   
   		menu.position = ccp(728,65);
   		menu2.position = ccp(40,65);
   
   		//[menu alignItemsHorizontally];
   		[self addChild: menu z:2];
   		[self addChild: menu2 z:2];
   
       }
       return self;
   }
   
   -(void)nextCallback: (id)sender {
   	CCScene *one = [One node];
   	[[CCDirector sharedDirector] replaceScene: [CCCrossFadeTransition transitionWithDuration:0.5 scene:one]];
   	//[[CCDirector sharedDirector] replaceScene: [CCMoveInRTransition transitionWithDuration:0.5 scene:one]];
   }
   
   -(void)previousCallback: (id)sender {
   	CCScene *one = [One node];
   	[[CCDirector sharedDirector] replaceScene: [CCCrossFadeTransition transitionWithDuration:0.5 scene:one]];
   	//[[CCDirector sharedDirector] replaceScene: [CCMoveInRTransition transitionWithDuration:0.5 scene:one]];
   }

   Any chance you have the error message logged in the console when it crashes?

   I don't know if you already fixed it but... here's my comments:

   Adding menu object twice in MenuLayer init.. I'm not sure if it's possible adding duplicates raises an assertion. Does [MenyLayer node] alone work?

   Sorry, I posted this code above as a working example. No Errors. It works. Doing it this way you can place menu buttons anywhere.
   The code in my first post was done in version 8.
