Well, you are correct in that the banner is an addition to the program....

but I think that the support is also linked to the fact the Wiinja team are listing all updates to this program in their official forums and I would guess maybe offering some kind of inside knowledge to the developer - maybe...

this could be a good thing, it might enable the software to be developed so that dumps can be made on any drive - maybe using the Wiinja code.

Just some thoughts, so might be completely wrong.
