I posted this question on the noob thread but have received no proper answer, so here it is. I have a US 2DS with sysnand 6.0/emunand 9.9, an EUR retail card (Pokemon AS to be precise) and Gateway red card. My idea is to play the retail card in GW Classic Mode; however it seems to be impossible to update an EUR card through an US system. The update notice still pops up even though I have already installed the EUR update cia. I can't play online without it being updated. Someone suggested unlinking the nands. It just doesn't work. They say GW Classic Mode can't boot any illegal .cia files (including update cias). So does my update cia. Is there any way to update my game? Thanks in advance.
