Yeah I thought it was just ndsplayer19576 shame may advice of updating the systems mods falls on deaf ears

As the USB Loader itself doesn't actually do alot except forward the instructions to DIOS MIOS it will not be a fault of the USB Loader itself it will be a system mod that is either out of date or has yet to be installed

If ndsplayer19576 does deside to use ModMii though don't forget to also re-install DIOS MIOS afterwards
