I don't have the mouse for Mario Paint and it won't work without it, but I would probably trade Animal Crossing for Sapphire. Can you please describe the condition for me, and can you tell me if you would be willing to ship first? I have done hundreds of trades through this site:

If you wanted to do the trade there we could do that, and that way if I ripped you off at least you could mess up my account (which isn't worth it for a copy of Sapphire to me). Either way, please let me know.
