I won't read through the 48 pages, so I'll just ask. Does anyone else have trouble installing the mset cia? For me it just says "Invalid CIA" when I try to install it from BigBlueMenu (I assume this is what they were talking about when they said "DevMenu.3ds", or maybe I am just using a wrong CIA installer...). I also tried with FBI and this is the same. I tried to install this to my SysNAND and to my EmuNAND, the error is the same each time; and of course I cheked the cia was correct twice.
Can anyone help me? Thanks in advance!
