I currently own a DS Lite and am planning on buying a 3DS in the near future. I wanted to buy a flashcart that I could use currently for my DS Lite and that I could use when I do buy a 3DS. I researched a little bit and found that the R4i Gold 3DS would be a decent choice for me. 1. Will there be any problems using this flashcart in either my DS Lite or my 3DS? 2. Is there a good chance that there will be an update for the 3DS that will make the flashcart inoperable? 3. If I emulate a game like Pokemon, for example, is it possible to trade between the emulated copy and a legit copy? 4. Is this website a legitimate retailer of R4i Gold? http://www.dwtechz.com/r4i-gold-revolution...ds-p-16963.html Thanks for any help with these problems.
