I did my best, I have no regrets!
It is not a DSi exclusive. Otherwise I assume the platform would say "Nintendo DSi" instead of "Nintendo DS".if this is dsi exclusive (it probably will be, and it will have a camera gimmick) I will go on a murderous rampage
Of the 125.13 Nintendo DS systems they have sold, only 17.13 million (13.7%) are DSi or DSiLL. I think they want to go for as many people as possible for now.
It might be like Gold / Silver / Crystal. Gold and Silver were enhanced for GBC but played fine on GB. Crystal required a GBC to play.
