Just bought a new 3DS XL, firmware 4.2.0-9. After reading the stickies, I want to get some things straight. First off, it seems like the two most popular flashcards are the R4i Gold and the Supercard DS2. Theres a pretty significant price gap between the two, so what makes the Supercard that much better/more expensive? Next, 3DS roms are not supported yet, but which flashcard has the most potential to be able to support them in the future? Thanks for the help.
