Donkey Kong (NES, Famicom Disk System)/ROM map

The following article is a ROM map for Donkey Kong (NES, Famicom Disk System).

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 respectively. Then increase the result by 10 to compensate for the 8 byte header. I.E. C000 = 0010, D2F8 = 1308, etc.
