Nintendont (GameCube) from within USBLoaderGX, using the same Hard Drive that I play Wii games from?

Is your hard drive fat32 or wbfs?

 

Try reading the 'excellent guide's on here to find out. Namely the NINTENDONT STICKY

 

Use FAT32, WBFS is shit and outdated.

 

split them with wii backup manager

 

Not true, Wii backup manager splits the games. FAT32 is the way to go

 

Also, games will be automatically split if you rip them directly from the loader

 

Don't format if you don't want to lose your games.
You can convert from WBFS partition to FAT32 and keep all your games.
look in my signatures, there's a tool and a guide to do it (wbfs2fat).

After converting to FAT32, you should use WiiBackupManager to automatically rename the games and folders correctly.
choose "Title [ID]" format in the WiiBackupManager's options and enable the "auto rename on mount" (it has another name, but you should find what I mean by looking at the menu's options).

The manager you linked is good, that's the one everyone is recommending.

 

,WBFS is a dead format now that we can use wii backup manager to inject wii games into a Fat32 formatted drive.

Just make sure all of the wii games are in the WBFS folder and the Nintendont games are in the 'Games' folder with all of the file paths correct, like game.iso etc. USB loader should pick it up properly with no headaches.

Make sure to use a good program like the wii backup manager; if it's above 4GB, it'll split it for you.
