These roms are denoted by position on the game board,
not the actuall part number.

Notes:
- Diamond Run doesn't use all the ROMs. d5 is not used at all, and the second
  half of d3o is not used either. There are 0x38 levels in total, the data for
  levels 0x00-0x0f is taken from ROM space 0x8000-0xbfff, the data for levels
  0x10-0x37 is taken from the banked space 0x4000-0x5fff (5 banks) (see the
  table at 0xc66f). Actually, looking at the code it seems to roll overs at
  level 0x2f, and indeed the data for levels 0x30-0x37 isn't valid (player
  starts into a wall, or there are invisible walls, etc.)
  The 0x6000-0x7fff ROM space doesn't seem to be used: instead the game writes
  to 6048 and reads from 6000. Silly copy protection?
