It's an ultra-powerful NewtonScript object browser / debugger. Install 1.3
and read the documentation. You'll want to dig into the PowerTrans package
and find the code that checks the registration, and then you'll have to write
a separate package that patches that function. I did something similar for my
RotateBook extension, patching the Newton's book reader to rotate the screen
automatically:
