the format is WBFS
Howdy,
Before you start reformatting, what game(s) isn't working? I'm assuming some games are working, but not others. Try checking the compatibility list here:

While WBFS is an old format, it does still work - FAT32 is recommended because it's easier to work with on your PC, and it's required for GameCube games and most homebrew.
it may be that the game you are trying either isn't compatible, or needs some 'massaging' to work.
You're probably running a really old USB Loader GX thenok, i tried formating it to a FAT32, but all of my games are .wbfs and usb loader gx wont read them.

here's the build a lot of people are using right now, the main developer/maintainer Cyan has been away due to a computer issue- so GreyWolf has taken over for a while.

Moving on from that- you should probably post your syscheck and I'll help ya with setting up your cIOS's and getting your current USB drive working.
