Sorry if this has been posted to death about, but I wanted a good answer before I threw down 40 buks on a DS2. Can DS ROMs run on any other flash carts? Are they all blocked? Does the DS2 still work for the 3DS? Where is a reliable trustworthy merchant that I can buy one from? What do you guys recommend if the DS2 isn't top pick for you guys. And lastly, what should I expect in terms of use and functionality. Thanks in advanced guys!
