I was wondering that, perhaps, the best way to 'hack' nx1 would be writing code for it. I mean, instead modifying the existing fw, why not just leave it as is and write new routines to be summoned from sd at startup? That should be possible as shown by those who have done something for this camera, till now. And these routines should 'intercept' some parameters and change them on the run. Eg. When I select video pro quality, set a higher bitrate. Or: when I set 120fps, run at 240fps and so forth...
