hello,
You are talking about the Channel installed on your console to launch USBLoaderGX, or the way USBLoaderGX interface looks like while inside the application?
The Channel used to launch the application is composed of 3 different things :
- a small banner animation (the one you see on your System menu when the channel is not selected)
- a big banner animation (the one you see in full screen with "back" and "start" button)
- a
simple picture ("USB LoaderGX" splash screen on a black screen) when you select Start, it's the "loading screen" you see until the read Application is launched from your SD card.
To modify the animated banners you will have to create new banner animation and replace them in the WAD file you used to install the channel.
To modify the splash screen you'll have to recompile the boot.dol of the forwarder channel and replace it inside the wad too.
Source of the forwarder :
https://sourceforge.net/p/usbloadergx/code/HEAD/tree/branches/USB_Loader_GX_Forwarder/
the used picture are in /sources/images/
The application itself can be themed, and you don't need to modify the dol at all.
there are a lot of themes available on this site :
http://wii.spiffy360.com/themes.php?category=1
with themes you can replace the default images, sound and element positions like you want.
To use a theme, you extract the downloaded theme file into apps/usbloader_gx/themes/ folder
You need this in the themes folder :
theme_filename.them
optional_Theme_folder/
example :
apps/usbloader_gx/themes/school.them
apps/usbloader_gx/themes/school/ all the theme's png picture here
in USBLoaderGX you go into settings > theme menu > select the theme you want to load. it will list all the ".them" files found in the themes folder.
