There are NO changes for NZ@McD1 in fw 9.3, so most probably it will work only with the streetpass data left by the same fw 9.3 3DS, so please continue to use windows script if it worked before for a several days more. Anyway most of you don't have another option, so don't give up and continue the test please
Do you recommend those who haven't updated yet to stay at 9.2?
