This is a subpage of ROM
  • 0x0000 to 0x0489 (489) = Code
  • 0x048A to 0x0493 (00A) = 1 word each.
    • Offsets for reading from SRAM. Based on an index stored at $70:1FFE, it will load the value $0000, $0500, $0A00, or (possibly) $0F00. The last value seems sketchy because that is an offset for the mirror of the first save slot.


  • 0x0494 to 0x05FB (167) = 1 word each.
  • 0x0494 to 0x049B (---) = Used in DMA transfers as local addresses in Bank $7E. See $0AD8 in the RAM addresses.
  • 0x049C to 0x04AB (---) = Used in DMA transfers as local addresses in Bank $7E. See $0AC0 and $0AC2 in the RAM addresses.
  • 0x04AC to 0x04B1 (---) = Used in DMA transfers as local addresses in Bank $7E. See $0AC4 and $0AC6 in the RAM addresses.
  • 0x04B2 to 0x05B1 (---) = Used in DMA transfers as local addresses in Bank $7E. See $0AC8 in the RAM addresses.
  • 0x05B2 to 0x05D1 (---) = Used in DMA transfers as local addresses in Bank $7E. See $0ACA in the RAM addresses.
  • 0x05D2 to 0x05DD (---) = Stored to $7EC013. The value stored is indexed by $7EC015.
  • 0x05DE to 0x05FB (---) = Used in DMA transfers as local addresses in Bank $7E. See $0AE0 and $0AE2 in the RAM addresses.
  • 0x05FC to 0x0E4B (---) = Code
  • 0x0E4C to 0x0E53 (008) =
  • 0x0E54 to 0x110E (---) = Code
  • 0x110F to 0x113E (02F) =
  • 0x137B to 0x1395 (01B) =
  • 0x1396 to 0x15F3 (25D) = 1 word each. Pointers to ROM Addresses used in DMA transfers. While these are local addresses, the DMA transfers generally use Bank $10. See $0ACC and $0ACE in the RAM addresses
  • 0x15F4 to 0x1851 (024) = Pointers to ROM Addresses used in DMA transfers. While these are local addresses. The DMA transfers generally use Bank $10. See $0AD0 and $0AD2 in the RAM addresses
  • 0x1852 to 0x1887 (345) = 1 word each. Pointers to ROM Addresses used in DMA transfers. While these are local addresses, the DMA transfers generally use Bank $10. See $0AD4 and $0AD6 in the RAM addresses
  • 0x1888 to 0x18AA (022) = 1 byte each. Upper byte of a series of VRAM Target addresses, that are used depending on the situation. Table is indexed by $7E0116
  • 0x18AB to 0x18BF (---) = NULL
  • 0x18C0 to 0x18DF (---) =
  • 0x1B52 to 0x???? (---) =
  • 0x4FF3 to 0x528F (29B) = Indexed (long) table to compressed graphics packets. Each of these packets is treated differently: i.e. $0A = Dungeon sprite
  • 0x5B57 to 0x6072 (---) = ???
  • 0x6073 to 0x---- (001) = graphics data? Appears to come in 8 byte chunks.
  • 0x7C9C to 0x---- (001) = ???
