Last week I've been very busy and I couldn't work on nethack. Today I uploaded a new build.
Now zooming steps are fine grained and a problem related to scroll bars has been corrected.
Next weeks I've been working on VLC, my first attempt on hardware doesn't work. I believe that I will have to learn about c55x DSP in order to optimize ffmpeg for Nokia 770 and this will be a hard task.
Good nethacking :)
