M!X preowned question

[Peej]

So I have a preowned Dream M!X on the way from Japan You Want, and I have a question about potential unlockables in it. I am assuming that it will probably be the closest it can be to being factory reset. If it still has the previous user's data on it, if they had already unlocked the mermaid and ninja places, if I were to let the tama run away so that I can go back to Gen 1 would that keep the unlockables, or would I need to unlock them myself?

if you let it run away and hatch a new egg you will not have to unlock the locations again

Sweet, thanks

And what's more, there's a chance you will have downloaded content on it, since in Japan ethere are M!X stations and that's the only way to get new content on them (mostly things like games and wallpapers).
