Hi i just got a DS the other day as did my girlfriend she live a few miles away from me i was wondering how could me and her chat to each other over the DS we both have the WiFi set up could any one shed some light please.
For text chat, you could try a homebrew like Beup Live, which is an MSN client for the DS. There's also ClIRC (IRC) and DSAIM (AIM) if you'd prefer those, although a lot of people have trouble getting DSAIM working. For text and drawing, the commercial game Clubhouse Games/42 All-Time Classics basically has a wifi version of PictoChat built in. For voice chat, I'd recommend the commercial "game" Diary Girl, which is exactly what it sounds like, but which actually has a surprisingly robust voice chat client built in. If you don't mind it being plastered with pink stuff, girls and flowers, it works extremely well.
That's the weird part. My switch is a lite one, mod-chip, SXOS 10.2.0. I followed a recent video showing how to migrate using the same model as I do, everything was fine until I hit the launch button and then atmosphere and this error appeared
