figured out that setting New3DS to 804Mhz mode breaks the multiplayer/co-op functionWireless is on, Both systems are on latest B9S firmware and Luma too, the second 3ds I don't even used it because as soon as I choose "Host game" it gives me the error message so I can't create a room. The game is on the latest version 1.1. I thought it was missing some kind of plugin or something so I went through this whole tread but did not find any kind of similar errors/fixes, is there some kind of plugin that I need installed on Luma to make it work?
Btw, I really appreciate you guys, and thank you for replying so quickly!
EDIT : weirdly enough, setting new 3ds cpu to OFF in luma v9 configuration during boot work fix it either, you have to return to homemenu after launched the game, enter rosalina menu and set the cpu to 286Mhz, and launch the game again.
even more EDIT : not that it matter anyway since the download play is region locked and gets an error on another client after downloading the download play data.
