It is basically an alliance between Nintendo themed wikis coming together to not get taken by wiki farms like Wikia, because they force stuff like skins on them. Though StrategyWiki, which doesn't only have Nintendo series, joined.
That may be right. But inspecting farther shows that it is a part of the line. It has DS in its name like others said, and has 2 screens, which is what DS stands for: Dual Screen.
In all technicalities, it is and it isn't. It looks almost exactly like a DS, just has different software. But that software is true 3D pop-out rendering software, something no other DS even came close to, making it what it is and isn't.
