I ordered this product on Sunday and it took 4 days to arrive. In the buying options section I saw sign that said very good. So I ordered it it came just as it was in the description! Oh by the way in order to unlock Luigi you must  go to the first save file hit start then it will say copy. copy the save file then go to the copied save file hit start again then go down to clear then hit the select button and then it'll say erase all data. All the data will be deleted but if you erase all your data you get to play as Luigi so yeah.. Anyway The seller I got it from is Sosa games. also really fun game!! It's also hard to!! Anyway I recommend this game to whoever is buying a GameBoy color or has one
