Alright. I hate making a topic that has most likely already been covered but I searched and found no clear answer. I just got a working 3 in 1 after my first one didn't fit and I have no idea how to set this up to work with the R4. Do I have to flash anything onto is via the R4 like firmware? What programs do I download? I just need a quick tutorial on what to do to set this up. Also, is it normal for the pack to not be flush with the DS? It seems to protrude by just a TAD. Not by a lot but noticeable by touch.
