Hi. I already have an R4 and I would like to get a slot-2 flash card. A friend of mine recommended the EZV 3in1 and so I'm looking at this. The question I have is whether or not this is all I need. Since it doesn't (or I assume it doesn't) come with a slot to insert a microSD card into it, how will I get games onto it? Is there another accessory that I'm missing? Any and all help is appreciated!
