I'm doing great with my Gateway but I keep getting SD/TF errors when I try to run the RPG game. I just picked up a couple new micro SD cards so I was wondering if somebody can tell me how I need to format the micro SD and SD cards to play them? Also am I going to need to use a new SD card other than the one I'm using to play my .3ds games so I don't lose my saves (or are they saved on my micro?) or is it okay for me to use the same SD card or am I going to format it differently so I can't play my .3ds games? I just need some basic step by step instructions. Thanks ahead guys!
