I'm trying to get this working but it won't work.
I transfered the .ISO file with WBFS manager 4.0 to an 500 GIG external HDD (the disk has no extra power supply cable.)
I downloaded the .wad files like you told in the tutorial and installed them trough MMM (i think there were 7 or 8 wads?)
After that i installed the cIOS trough the wad files, i restarted my Wii and launched the USB Loader GX.
In this loader i can see the game between the other games in the list.
Then i go to settings > Game Load. In this list i see Game IOS where it says "USE GLOBAL".
If i select this i type something. In the space where you can type something it shows "-1"
You can max use 3 characters (i suppose i need to fill in there a number like 245)
I don't know good what to use and how it needs to be done further.
Can someone help me?
