Reecey is the one in Europe who hasn't gotten banned doing the cert's. They have the xbox 360's in their avatar.
iirc you want the biggest game available for that cart type. Zelda is good because it's a large cart (16gb)
so for type 2 you want a 16gb as well (the largest type 2 card available). Wolfenstein 2 will work. I believe that's what reesey uses.
You can find which carts work at this site

Just filter imagesize from largest to smallest. If you scroll all the way to the right it will show the cart type (1 or 2). conveniently, when you filter by cart size it also sorts by cart type so you can easily find the 16gb type 2 carts you can use for your type 2 donors.
hope that helps.
