I have a 2DS with V 9.2.0-20U firmware. I want to run mainly a couple DS games, but also a few 3DS games. What flashcart can I get to do this? Or will I need 2? From what I understand, Gateway will run 3DS roms, but only on the new update which comes out soon. As for Gateway (Blue) running old DS roms, I need V4 firmware or lower? Or can I just get an R4i Wood/Gold 3DS for my 2DS and run old ROMs like so? Or a DSTwo?
