I understand that there is nothing that can play 3DS Roms. I'm quite surprised nobody has managed to break it all this time, nonetheless, no matter. But you can at least play DS Roms though right? This is where I'm a little lost. I've searched but I honestly don't know what I need for this. I don't know the difference between all these cards. What's the cheapest thing that I can buy to be able to play DS Roms on a 3DS? What's a reliable place to buy this from? Can I find it on eBay? Is there a tutorial I can read? Do I have to install something? How does it work? Do I need to do anything with the 3DS firmware? I'd appreciate any help. I know it's a lot of questions.
