I had an old version of USB Loader GX that didn't have support for Nintendont. I got the one that does and now my Project M ISO doesn't show up now. Anyone know how to fix it? It finds my Gamecube games fine.
what is the path to your SSBB game?
/wbfs/Super Smash Bros Brawl [GameID here]/gameID.wbfs ?
if not, rename the folder to match this one.
Then in USBloaderGX be sure to display wii games (4th icon in the top menu).
