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.
Note:
DMA offsets for Bank $7E (usage undetermined as of yet. Probably pointers to font tiles)
