Summary: Firstly i would like to say leaf green gets 5/5.. however.. the copy being sold here is fake.. you can tell its fake, Firstly, by when saving the music stops.. Secondly by when your gaming device reaches low power.. the save deletes its self and you lose everything!!! This is because unlike genuine cartridges it dose not have a separate chip for save data Thirdly when the cartridge arrives.. if you look inside you can see the word "Nintendo" is not etched into the Chip..
Summary: I love the game, infact I love all pokemon games. The only problem these days is trying to get a hold of a legitimate pokemon cartridge for a reasonable price. I advise you to contact the seller you wish to purchase prior to buying any cartridge and finding out if the cartridge they are selling is a legitimate one, also don't feel that you are being rude if you ask them if they know how to spot a fake. Do your research so you know yourself if what they say is true.
