Please, do not buy this product.Having owned this before, and used it before with great success, I decided to relive one of my old games, so I had to re-buy this product from this seller.Yes, I used the Master Codes.Yes, I checked different websites to make sure the codes were correct.Yes, I entered them correctly.Yes, I double checked after I saved them.No, this product DID NOT WORK AT ALL.There were even some tries where I wasn't able to select the game at all.Do NOT waste your money.You think that I don't know what I'm doing, or that it'll work fine for you?Don't say I didn't warn you.
