Today I tried to setup Dolphin with retroarch 1.8.2 but it does not work. Only black screen. I tried the same setup with 1.7.7 and it was working. Has someone also those issues?
Seems like that is the issue:
Seems dolphin is not usable anymore with the newest retroarch versions 
Have you tried going to settings > core > let cores change the video driver OFF?
Yes. Does not work anymore. Your have to switch to the vulkan driver.
gl and glcore are no longer working on the Dolphin emulator.
