Im completely new at this but I have a nintendo 3ds xl and it is ver. 4.5.0-10U and i have downloaded the latest wood firmware V1.56 and am using the newest r4i3ds gold card when i put it in it is a metroid prime icon and will not load at all. nothing when i use it inside my old dsi that has never been updated it works perfect. is there something i can do to fix this or that im doing wrong?
