I know I'm most likely way too late to give an answer that will help you, but I'll answer anyways to help others that may have a similar question. This is 100% normal. The Nintendo logo that is displayed is stored on the cartridge, and the Game Boy checks if that matches the one it has. If the data it receives doesn't match (or no data is received, as with your case), the game won't play. This was the Game Boy's bootleg protection, because if an unlicensed game displayed the Nintendo logo, they would be prosecuted for copyright infringement. Again, this is a normal and intended function.
