"Would it be possible to turn off bi-linear filtering on the sprites?"
and
"sprites still look blurry when windowed"
This is not DBPro making them "blurred" by default - it's a combination of your video card settings and directx settings (for that card). I have mine turned off, but it's not always an option and sometimes when in Window mode the card will default them on anyway. There could be no "unblur sprites" command, but rather access to directx aliasing.
Unsurprisingly using a memblock and direct pixel writing equals no aliasing at all, but this is useless for games really.
