One word per room (0-33): the display-file address where the room's animated marker (24x12 pixels) is XOR-blitted on that room's deck map. Read by GetRoomMarkerAddr (35088), which feeds both marker channels: A — the walking crew figure (CrewWalkA1/A2) on the room being viewed, placed by PlaceRoomMarkerA (35101) — and B — the blinking box cursor (RoomCursor0-3) on a candidate room: an exit row under the cursor in the room view, or a room picked from the Indicate Location list, placed by PlaceRoomMarkerB (35128). Rooms on different decks may share an address (Cargopod#2/Mess); the Narcissus (34) has no entry.
