Chip tiny.png The following article is a ROM map for Final Fantasy IV (SNES).

Japanese

Pointer tables are at the same bank, that seems to be split in two like the dialogues (32768 bytes).

  • 0x57000: boxes and font, 2BPP (NES).
  • 0x70000: listing and battle dialogues.
  • 0x80000: general dialogues.
    • 0x8070B (0x80709 in Easy Type): first dialogue.
    • Split in two parts, the second one begins at 0x88000!
