Atic Atac: Routine at 39122

Used by the routine at StartGame.

Called when a game starts. Chooses the rooms for three of the keys from the three tables of rooms that follow, using FRAMES and the counter at CounterLow. The green key (Initialisation_Key_Green) uses FRAMES, the red key (Initialisation_Key_Red) uses FRAMES plus the low byte of the counter, and the cyan key (Initialisation_Key_Cyan) uses the high bytes of both. The room of the red key is also given to the mummy (see Initialisation_Mummy). The yellow key does not move.
