I have no idea what to do. In India, I was able to find these for a reasonable price: http://www.amazon.in/s/ref=nb_sb_no...d-keywords=r4+card+dsi&rh=i:aps,k:r4+card+dsi I want to run DS ROMs(and hopefully GBA and NES?) on my DSi, and later on a 2DS. Which one should I buy? Or do I need to buy something else? Where can I start generally? I have a Pokemon Volt White 2 ROM(ROM hack of White 2, which I own), and have emulated it before, but not much else.
