Hey! First of all, sorry for my bad english. I try to install the cia of Detective Pikachu on my O3DS FW 9.2.0-20E. The cia is on the sd card and Big Blue Box on my Gateway card as a .3ds-file. While installing the game, i get the error, that the cia is invalid. Is my firmware to old for the game, so that I have to set up EmuNAND or is it impossible to play this game on a european 3DS?
