I just bought 3 pokemon DS games from a local seller. I actually did tons of research on differences on fakes and authentic, yet I could not find anything wrong with these cartridges so I bought them. So far I've played about 4~5 hours into the game, but no issue. But just in case I missed out on a detail on fake cartridges, can someone take a look at them let me know if they are fake or authentic? If they are fake, I would like to return them before it is too late. If you believe these are fake, could you please address why so that I can bring it to the seller?
