So I've just upgraded from an old Supercard CF to a shiny new R4DS. My DS phat is currently flashed to allow use of the Supercard but I'm wondering now if I'm better off putting the original firmware back on now I have the R4. Will replacing the original firmware give me any better or worse compatability with download play? If it makes no difference I'll keep it flashed just to have rid of the Health warning nag screen.
