Nintendo had mentioned an app that would be released to allow people to convert saves from cart to digital.
Only for select games.
I expect it would be for games which released in retail first then had an eShop release, maybe for succeeding games that release for both as well. Probably for first-party title first, then maybe third party.
pardon if my posts suck, i post by tapping on the handset button on a one-way analog handset. i saw Hannibal Lecter do it.
Ah cool thanks for the replies. I still have the cart, and I don't imagine I'll sell it, but the idea of having a bunch of 3DS games already on the system is very appealing to me. Especially because I use a 32GB SD card.
