I have a homebrewed Wii (ver. 4.3E) with d2x cIOS installed on it. I use USB Loader GX to run my COD: BO WBFS file from a 32GB fat32 SanDisk USB, but the game always gets stuck on the loading screen. I can run other games, like Smash Bros and Mario Kart perfectly fine via USB Loader GX, but COD: BO doesn't seem to work. How can I fix this?
