Summary: This is my second purchase of Mario Kart DS. I bought this product a few years ago and it was very fun! I wanted to buy another one so I bought one a few days ago, as a gift. It came very fast so I plugged it into my ds and it was FAKE! It didn't work and the game didn't show up in my DS menu! How to determine fake Mario Kart games (some criterias apply to all games): 1. LOOK at the box/picture posted on Ebay!
