I've gotten quite a bit of DLC but I just realized you can't so easily change the slot numbers by renaming the files... So I was hoping someone still had the Slot Changer program or at least new of way to get the slot numbers changed. Thank you!
Didn't know the link was down. I'll reupload it when I have some free time again, should be around Monday afternoon.
