So I originally was going to get a supercard dstwo for the gba emulation but ive decided to get an ez flash IV instead for my gba games since I still have my GBASP. so now im strictly looking for a ds flashcard for my 3ds. 3ds firmware is 6.3.0-12E. Im looking at these . R4I dual core. http://www.trademe.co.nz/gaming/nintendo-3ds/accessories/auction-673896986.htm R4I A GOLD. http://www.trademe.co.nz/gaming/nintendo-ds/accessories/memory-storage/auction-676206192.htm R4I RTS 3DS. http://www.trademe.co.nz/gaming/nintendo-ds/accessories/memory-storage/auction-673808940.htm Which would be the best choice?
