1. I diligently followed the guide here to the end: https://wii.guide/
2. everything appears to be installed ok.
3. Using Wii Backup Manager I transferred a game ISO to the WBFS folder on an external USB hard drive (not a usb thumb drive). I see the MarioKartWii [RMCE01] folder in the WBFS folder.
4. when I open USB Loader GFX I see the Mario Kart Wii game that I copied to the external drive.
5. When I try to launch the game I see a Mario Kart Wii loading screen with a 'settings' button and a 'start' button. When I click start I get a black screen and after about 30 seconds it returns me to the homebrew screen
6. I've also tried 3 different games and verified they all work in Dolphin.
