Real NEC freaks have already found it and have fired up Nero CD/DVD Speed. Finally there is a firmware available that allows NEC users to use
the quality scan feature of Nero CD/DVD speed. The firmware has been made
available by forum member andrepappy and is according to him based on an IoData firmware. Currently only NEC ND-3520 are the lucky ones to be able to use this feature. For more information you should read the following thread in our NEC forum.
