How much trade-in cash would I recieve at gamestop for the following items?

You might not be able to trade the GBA games at gamestop because they have become a collectors item. Also, a lot of the sports games before 2009 you will have a hard time to trade in because not every gamestop accepts them. You will have to go to different gamestops to see which one accepts them. With the stores that do offer the sports games to be traded-in, you would only get about a dollar for the older ones and for the latest games, you would get a little more.
