I started a new PBR save in slot 4 and connected it to wiimmfi. I received a Friend Code. Now I am trying to load the friend codes from the Pokemon DS games into PBR roster, but it is rejecting the registration. I even dumped the WiFi connections on the DS consoles and received FC from wiimmfi for the DS games, but the PBR is still rejecting the FC even when both the PBR and DS are freshly received from wiimmfi.

It appears that the PBR FC and the DS FC are not compatible. I tried to load the PBR FC into the DS Pal Pad, but it was rejected also.
