The loader is provided in two different formats :
1- installed on the Wii (standalone version), it appears as a Channel on your system menu.
2- located on SD or USB, a "boot.dol" file launched from The Homebrew Channel.
1- The first one is the Full Channel, the program is installed on your Wii internal memory and launched through the channel. To verify that you are using this version, launch the loader and go to Settings > Credit.
Look at the top, if the version is followed by a "c" (3.0c) then you are using the Channel version.
This version is not updated anymore (because of missing updating code in current version).
2- The second one is the "boot.dol" version. the USBLoader's main program is not installed on the Wii memory but stays on your SD card or USB and you launch it from The Homebrew Channel.
the program must be located here :
SD:/apps/usbloader_gx/boot.dol
or
USB:/apps/usbloader_gx/boot.dol
To launch the boot.dol, you go into the Homebrew channel and you launch it.
3- But there is another method to launch homebrew called a "forwarder".
Forwarders are Channels installed on the System menu, but doesn't contain the program you want to launch. It contains a little program which reload another program (it forward) located on SD or USB.
The Forwarder for USBLoaderGX reload the "boot.dol" located on your SD Card or USB.
The advantage of the forwarder is :
- You have a channel on your Wii, you don't need to launch the Homebrew channel first.
- You can update the program without reinstalling the channel every time (the channel is a forwarder, the program is on SD). Just update or replace the "boot.dol" file on SD card and the program is updated.
Disadvantage is that you need the file on SD or USB, but you already have an SD or USB inserted if you plan to launch USBLoaders (to store game covers, settings, cheats, etc.)
To check if you have the Forwarder, launch the loader from the channel, go to settings > Credit.
If you have "3.0" without "c", then it's the forwarder.
To differentiate the Full Channel and the Forwarder Channel, you can also use their TitleID.
On Wii, all installed program use TitleID. When you install the Wad file, the TitleID is often displayed.
Full channel has TitleID ULNR, Forwarder channel has TitleID UNEO.
If you want to install the Forwarder, I recommend to remove the full channel first (to prevent confusion).
Use a Wad manager and the Full channel wad, select "uninstall".
Then use a Wad manager and the Forwarder channel, select "install". and place these 3 files on your sd card:
SD:/apps/usbloader_gx/boot.dol
SD:/apps/usbloader_gx/meta.xml
SD:/apps/usbloader_gx/icon.png
The files are located in the
install package.
then update your loader.
