Hello, I am using Arcadia 6 Plus for CoinOPS Next 2 and I am unable to get the Wii games to run. RetroArch Dolphin-emu launches but no games load. All other consoles/games works with no issues. Does anyone know how to fix? Also where are the Wii game files stored? If I am unable to start the games I would like to delete them to free up drive space. Thanks in advance. :))

Edit: I was able to resolve the issue by changing the video driver from glcore to vulkan in retroarch. I would still like to know where the game files are stored so that I can delete. Please advise. 

Edit 2: I found where the files were stored and was able to remove them successfully.
