I was wanting to backup games on portable HDD for the wii and be able to them so I started looking into it. I came across this helpful youtube video: External Link Removed
I followed what he did and got the HBC and followed his instructions on how to get USB Loader GX installed and working.
-Run homebrew channel
-Run "IOS236 Installer/Uninstaller" ; Press 1 to install IOS236 and wait for the message on the screen "Getting IOS36 revision 3351"
Now, select the option "Load IOS from SD card." When installation is finished, press any button to return to HBC.
-Now, load the "CIOS rev20b Installer" app and choose the IOS 236 on the first screen using the D-pad and
button A. On the selection of IOS base, choose the "IOS56 v5661" , then "IOS 249" , then "WAD Installation" and then, "Wii SD Slot"
When installation is finished, press A to continue the process. Now you'll have to install the IOS250.
Again, you'll have to select IOS Base, and select "IOS38 v4123"(but this time install IOS250 instead of IOS249) and then again, choose "WAD Installation" and "Wii SD Slot." When finished, press any button to return to HBC.
I followed his instructions to the letter so I have the same file versions as he says.
So I got it working first time, backed up my Monster Hunter and started playing it... all seemed good and I was very happy...
BUT... after a while the controller stopped responding, the game didn't crash because it was still animating... I thought "meh w/e" and reset the console. After the reset I could no longer load up the USB Loader, it kept getting stuck on the "Loading" screen for it.
Did a little bit of googling found out that there is a much more up to date version of it... v3... So I downloaded it and installed it.
Now I can launch USB Loader and select a game... however when it is trying to launch the game it comes up with error #001, unauthorized device detected.
