I decided I would like to buy a GBA flashcart for my Nintendo Phat DS. I currently have an R4DS and I would like a GBA flashcart that will work with a R4DS. I am currently looking at the EZFlash 3in1 and the Supercard MiniSD. Can anyone tell me what makes both of these cards different? And can people suggest cards that are better than these 2, if any? Thanks, LiangJai.
