Release notes:

I started making a new firmware, and you can download on http://zzo38computer.cjb.net/fwnitro.zip. It doesn’t do much yet, but you can see what it does do. I got an example and changed a few things. Can anyone help me how to do the rest, anyways? Press up/down to move cursor, left/right to adjust, select to select, start to go back to previous menu, L to swap LCDs.
