The main issue, as I understand, is the different memory layout or structure for the 6618 or the 2 C489...
But why don't 'search' this forum topic with keyword = 'C489' ? ....
You can find this, as I did for you :

or
Upgrade or repair a 6618/S45 (3318/ME45) to S45i if you have a C489 flash eeprom
there you go !
