I made something like that. I combined wudump and wud2app. It dumps the app to /install/<disc name>/. After that you can just use wupinstaller..Will there ever be a combination from wudump,(wud2app) and wupinstaller in 1 homebrew? I mean a "disc2app"
And I named it before I saw it mentioned in your post, so we thought about the same name
It is much faster than wudump because it only reads the necessary parts of the disc.

I will open a thread on it later.
All the credit for FIX94 of course, I just merged his tools.
