well I just bought one, and ya its works perfect :), I have tried about 15 backups all of them have worked. The only problem is that certain homebrew apps are for other flash cart systems and even then you have to set them up right, like with this one app that lets you voice chat over the ds, or an online messaging program that allows you to pictochat with others, the IRC channels work great though, needless to say, it ownzzz
