Just picked up a 3DS XL today running stock firmware 4.1.0-8U. People here seem to recommend the Supercard DSTWO as the best all around flashcard since it's the only one that can also play SNES & GBA games. Is there any way I could play Genesis games using the Supercard DSTWO? Do you know if any retailers will set it up for me beforehand so that it works on the 3DS XL without any set up (I don't have a DS). Thank you very much for your help in advance.
