I use cfg usb loader, and I was using dios mios. however, a friend of mine, who had suggested the loader, mentioned using usb loader gx now due to nintendont not being supported. here's a supported version. my original cfg usb loader mod didn't, or rather wouldn't, update, so u can update with this version which is a later version than I was using. remember to rename to boot.dol....
