So I imported all my .RVZ Wii game files into launchbox. When I tried to launch the games using the dolphin emulator, it gives me a black screen and then crashes. I read that I may need to upgrade my launchbox? However I can’t do that with a license I have as I can’t update beyond April 2020. Is it necessary to upgrade or is there something else that can be done? Thanks for all your help in advance.
