Used by the routine at START_GAME.
Writes into INITIAL_STATE before START_GAME copies it: the rooms of GREEN_KEY, RED_KEY and CYAN_KEY, each one of eight from RANDOM_ROOMS_ONE, RANDOM_ROOMS_TWO and RANDOM_ROOMS_THREE, chosen from the frame counter. The running values at $5E12 and $5E13 are added in too, but they have just been cleared, so green and red use the same index. The mummy goes into the same room as the red key. The yellow key's room is not touched.
