I wish they will leave some kind of "engeneer menu", but i bet they willn't
I asked them if they could add something called "Player Configurations" menu and then underneath it add this roll off selection and possibly other setups as well when it is felt it is needed.
I'd be very surprise they will, somehow the easy simple way for them is it to just sell them as hot cakes and then move on. I gather if I was an electronics shop I would most likely emphasize the hardware release instead of software, it's all about financial and economy of scale. But again, this is not an Apple Computer corporation where those guys have an army of developers to add features to the dap, not to mention decent QA and manual to boot. So let's be happy they are as responsive as one can hope for a very small company.
