Think I'm already using 10.2 firmware.bin, NTR booted successfully. And that fixed my issues with MM and Tomodachi Life. Thank you for the help, been trying to get this solved all day. xD Do you know if there is a list of games that have this issue?
Not that I know of. I live in the US so the only out of region game I have is the EU version of the Kid Icarus 3D classic which does not require language emulation (got it from the usual place and then used funkycia2 to get the latest version, and of course funkycia does a region free patch by default).
