Well, I Fixed it - MH4U Ep4

Random Weapon roll: Charge Blade (wooo!)

Yes, I hate Gypceros. I suppose that's not too surprising. Damn shame CB got nerfed in GU. I still encourage folks to give it a go though. It's less "potent" yes, but it feels like I use more of the weapon's move set. For better or for worse.

Tl;dr on breaking Citra: overloaded my RAM repeatedly until computer didn't know what do. Delete openGL folder in Citra config = fixed.
