Hey, just to be sure i hope some of you encounter also the "ERROR" message, if you try to make a RAM Dump in the Gateway Cheat menu on a 128 GB MicroSD card. I tested the same 3 Games.. • Fire Emblem Awakening • Story of Seasons • Bravely Default with a 32 GB MicroSD Card and a 128 GB MicroSD Card. Only the 128 GB had that problem. Everything else is working fine with the MicroSD. Some other Infos: Old 3DS with Emunand on 10.3 (EU) No CFW or anything Both MicroSD's are form SanDisk. //EDIT 46GB / 128GB in Use. H2testw without problems.
