Of course, the only way to know is to try. I don't
have a PAL programmer
handy and wouldn't like to open up the machine again without a good

original analog board and restore the original components to the
machine. So this isn't something I will do right now, but it might
happen by the end of this year.
I did it on mine, all pals are protected :o(
