How to get 10 dollars before wednesday?

I just agreed to buy a game boy color and 2 games (Ms. Pac man and We're Back) from one of my friends for 10 bucks. One of my friends is going to let me borrow Super Mario Bros Deluxe and another friend is going to let me borrow pokemon versions Crystal and Gold. I want them so bad!!! But I don't have 10 bucks! I asked my mom if I could work for or borrow the money, but she's broke too. I don't know anyone else who I can get money from. What can I do?
