I bought this cartridge of Pokémon Emerald in a thrift shop. The seller wasn't sure himself about the cartridge, but I bought it anyway.
Playing it, there doesn't seems to be any difference in-game, so I can't differentiate based on the content.
What make me still think it is fake is that chip at the very left side, the second largest one. Even then it looks like everything is authentic.
It looks like they ran out of a certain chip at the factory and said 'screw it' and used a different type. You can even see the lines are for the authentic one and so they just made the wires longer.
Is this cartridge real or fake?
