I am struggling to use some legit CIAs from other regions on my Japanese O3DSLL running ReiNand 10.7. Both MH4U and Zelda: MM crash at startup with an error message saying that an error has occurred. The error on MH4U occurs as soon as the game is launched and tells me to force a reboot using the power button and contact the service centre if the error persists. On Zelda: MM the error appears after the small loading icon in the bottom right corner of the screen. The game exits to the main system menu and says that an error forced the game to quit and then the console soft reboots itself when the A button is pressed. I have tried clean reinstalling it several times and destroying the save file but nothing seems to fix it. I think both CIAs are EUR region but I am running ReiNand 3.5 which I believe is supposed to be region free for CIA's. Can anybody advise where I might be going wrong?
