Everything works i would think....now this is nothing to go replacing your stuff over, but if you want a few used buttons/sticks for something then hey it's Free.
there are i think 3 new buttons in here as well. These are out of my old machine....they were to go to ClubNinja i think but i forgot all about it and he has now passed.
so yours free......free shipping, but if you feel free to send a few SMB/DH carts or something my way..all the better.
