I recently swapped my 3DS LL 32gb Sd card out for a 64gb SD card. Everything is the right format (Fat32 via guiformat, 32mb data clusters). The 3DS reads the installed game files from the SD card when in sysnand (the installed CIA's show up on the home screen in sysnand). The issue is that when I launch gateway emunand from the internet launcher, it black screens for about 15 seconds and the crashes out to the sysnand home screen. when I run diagnostics from the gateway menu it tells me that everything is fine. This is my first dip back into 3DS exploits after almost a year. Am I doing something silly like missing an obvious step? or is this a corrupted emunand? Japanese 3ds LL running 8.1xxx firmware. Gateway 3.7.2 zip download, running Gateway Ultra 4.2 beta from within the zip package.
