Hacking Where are the disc channel images located in the systemmenu?

[WiiUBricker]

I'm interested in the images of the disc channel. I know they are somewhere packed in a systemmenu wad.
I downloaded a system menu, extracted it to a folder and extracted the app files with U8 tool, but I cant seem to find them.
Any hint?
