may i ask what the Bertmod ZPM fix is? I only know bertmod 0.4 so far.

I haven't used the latest Bertmod versions, but ZPM's fix used to make Bertmod prettier and more useful. If this link doesn't bring you directly to the original post from ZPM, it's post #35 that contains the download link. It still works on the latest firmware:
