Donkey Kong:ROM map

PRG ROM is mapped from C000 to FFFF. All the addresses below correspond to this. In order to find the data in a .nes file simply subtract BFEF from the values below. A simple method is to change the first digit to 0, 1, 2 or 3 depending if it is C, D, E or F repectivley. Then increase the result by 10 to compensate for the 8 byte header. I.E. C000 = 0010, D2F8 = 1308, etc.
