Who knows about nintendo's?

[pinkpanda3310]

My daughters friend came for a visit with her Dsi XL and tried to connect with my daughters 3ds. Lots of head scratching and we couldn't work it out. It accurred to me that it might be the regional barr and the 3ds. The 3ds was bought in Aus while the other was Japan.

Does anyone know how if the regional barr is the problem, or have any hints'n'tips I might try next time? Any help appreciated
