Authentic Cartridge only, it is tested and works, but you will need a controller pak to save your games. I have some listed on my store. Game has some label damage so it's a great copy to play. See pics for condition and I'll try to answer any questions you may have! I ship out quickly, and I pack your item appropriately to reach you unharmed. Thanks for looking!

I do my best to combine shipping costs to encourage more eco friendly shipping through bundling. It should combine automatically, but if it isn't working, please contact me and I'll see what I can do.
