Hi guys I have a new 3dsxl on 9.0 with gateway and using CN to use my GW. I have a private header from a MK7 retail card and I use it on every rom I play online with. I have this problem on mario tennis open. The game hangs at "finding players" window. It never seems to find any player to play with. I have applied the header correctly and renamed the rom to 3dz as I usually do with every online rom I use. Any thoughts?
