I was thinking picto chat should go online.Then i found this website in google.Seems you can hack your ds to make picto chat go online 
i myself…wouldn’t fuck with it…i dont enjoy the feature too much, so rather than mess with a perfectly good situation for me, i think ill stay out of it, lol.
Pictochat is fun if you have friends with DSs but I wouldn’t use a version someone made for online use, for fear of someone hacking into my system.

What the hell would be the point? Picto Chat is just a little useless program built into the DS that lets people chat. Making it go online would be exactly like MSN Messenger or AIM. And since you have to be in your house, why not just use a computer program?
