Unfortunately, I won't be able to work on NDSMail for the next 7 days or so.
It seems there are some problems with mini-SD flash cards (SC miniSD,M3 miniSD). This is rather strange, as they should be compatible to the SD cards. I think this is caused by the special version of the fat lib I'm using. The new libfat looks very promising, but it does not support the SC SD yet.
If I had one of the flashcards causing trouble, I could improve compatibilty ( hint hint )
a friend of mine proposed a great feature:
If none of the preferred access points is found, the app will try to connect to any of the (open) access points in range. So if you are in a public area, chances are that you will find an open, non-protected access point. (Note that this may be illegal in some countries. But I know that at least in germany you are allowed to connect to any access point that is not protected).
