Where can I get a new battery cartridge for the Mozart Magic Cube?

@wallace3 this may be tougher than anticipated. Replacement parts are not readily available so we may have to find a place to scrounge parts for the repair. Post some pictures of what the battery compartment looks like with the damaged area. That way we can see what you see Adding images to an existing question There may be a way of repairing it with some basic skills. If not than we can try to find a non-genuine replacement to make it fit. You could of course check places like ebay.com and see if something like this will work for you.
