nk.nb0 windows ce 7 reverse engineering

[FernandoAl]

I would like to try to reverse a firmware of an old car radio that has an arm cpu and windows ce 7. I have extracted all the files from the firmware including an nk.nb0 image but if I try to open it directly with qemu, the image is not loaded.
Is there a way to try to open this nb0 image or recreate the same environment on which to run the files to be examined?
Thanks
