Mupen Plus Next Black Screen

I updated all my cores when 1.7.7 came out and now I can’t get Mupen to work at all. Mupen plus next just displays a black screen but I can hear the game’s audio running. Regular mupen just crashes outright when I load any rom.

Is there some new requirement with these cores or something? I noticed a bunch of new video drivers in the options and none of them work with mupen on my rig.

I have an AMD gpu and I’m using win7 x64 with the regular GL video driver in retroarch.

Cheers.
