Welcome, and enjoy your stay!
I've been meaning to play Bravely Default, along with finishing Persona 3 FES, playing PS4 Golden, and SMTIV... Buying JRPGs is such a good way to add to your backlog.
It might be worth upgrading to the latest version of Dolphin first, its got a lot better since 2.0. Otherwise OpenGL, and leave force texture filtering off. You can leave everything else as default.
Thank you? Its very belated... I see you left 2 years prior as well. Was there any particular reason that compelled you to give birthday greetings 3 months late to someone you don't know? Not that I mind ofc. :P
