EMS Productions is selling a usb adapter for commercial nds games (product page). They claim that it will transfer saves to and from ds game carts (although they do say that third party game carts may not be well supported). Has anyone used this? I just got an R4 and I'm looking for a cheap way to get my existing game saves from my commercial carts to my flash cart (I don't have a slot-2 device). They list the NDS Adapter at $11.99 US which I would gladly pay to get all of my saves back. I just want to know if anyone can vouch for the quality of the product. Any users out there?
