I tried opening my own JPN fs3d non region locked and firmware spoofed cia and it went to the black screen with "An error has occured, turn off the system". The .3ds came from bigbluebox and the cia never worked. I requested a user on a different website to try to convert it to a cia and he also got the error. Is there any fix? We both also checked our KeyX's and they were both correct.
