This copy of Mario kart double dash has been signed by Charles Martinet himself! Was until recently voicing Mario, Luigi, Wario for Nintendo! Only downside is he personalized it to me Jeremias as you can see in the pics, I didn’t have the heart to tell him I didn’t want it personalized. You can see in one of the posted pics me with Charles Martinet holding the game in my hand after he signed it for me as proof of authenticity I also can show screenshot of the charge on my card statement from Martinet for the picture and autograph if you need further proof of authenticity. This copy of Mario kart double dash also comes with the bonus disc! Both discs have also been professionally resurfaced and now look like new, both discs have been tested to be working! Also has all original inserts and manual all in very good condition note the pics! Please study all pics very carefully and only bid if you are serious about purchasing as I do not accept returns. Thanks for looking! If you have any further questions or concerns feel free to contact me! IF YOU LIKE THIS COLLECTIBLE ITEM PLEASE CHECK OUT MY OTHER ITEMS LIKE THIS I HAVE FOR SALE!!!
