Hacking Wii games show up but gamecube games dont.

[bunique]

I am currently using Configureable usb loader v7.0, I finally got my wii games to show up and work, but still struggling for gamecube games to show up on the loader, I have tryed to place them in the wbfs folder and games folder, still they dont show up, damn what could be the problem????? i have put them in the right path structure ex: usb:/wbfs/[gameID]_title/game.iso, or usb:/games/[gameID]_title/game.iso, no gamecube games show at all, this is really irritating why my wii games only show up, but not my gamecube isos, could someone help me out please? i have installed dios mios 2.10, still nothing. theres gotta be something i havent installled or something like that. need help asap! also im using fat32 flash drive if your wondering, heres what basic settings say:
