A cab creator should actually be really simple, since all it is is an xml file and other files that are renamed... I'm not exactly sure what the naming scheme is of files in cabs though... if someone could fill me in?

And the default icon is controlled by the exe as far as I know, unless there are registry edits for it... I don't know too much about that.

And as for actually converting .bmp to .brn, is it a simple extension rename, or is the picture re encoded?
