Hey there. Since I downgraded my 3DS to 9.2 to install CFW and setup emuNAND, I went to get a DS flashcart. The one they had available was that 2014 white R4 3DS "upgrade" (http://www.r4isdhc.com/wp-content/themes/nds9/images/DUAL-CORE.jpg) My question is, what else can be done with it or what are its benefits? My old flashcard was a TTDS, and this seems to be a great update. What does the Dual core thing do? (plays GBA games or something like that?) Any other feature the cart might have?
