USB loader and Nintendont GameCube ISO issue 😬 Any advice?

Update Got the issues solved with someone else on here’s usb loader and Nintendont app files pre configured Just setup usb loader and nintendont on my Wii and made a folder on my 32GB USB called “games” and then sub folders for the name of each game and named the game iso files “game.iso” and inside nintendont I see the games and they show up in usb loader and have the title path for the games set to the game folder and it will create/load the save file and after it’s finished it’ll switch to a black screen and just stay there, same result with my like 5 different games. Any ideas? I can upload pictures of my settings/config if needed (: thanks!
