Interesting. Thanks for the mini review. I still own just a DSi-XL and haven't upgraded to a 3DS yet purely because of the lack of flash cart support. This definitely sounds useful, although I don't like the way you have to change games.

How does the Gateway work in comparision? Does this load 3DS and DS games? I'm not too bothered for DS only games as I have my XL with a acekard 2 cart.
