Now you got to find Trottier. Alain Trottier is the guy in the brown suit and grey hair. Talk to him. Tell him you're Indiana Jones from Barnett College. If you tell him you're the greatest adventurer he'll tell you go bug off. In this case, go inside the hotel and talk to Sophia.
She'll tell you to name drop Nur-Ab-Sal. Go back down and talk to Trottier again and tell him Nur-Ab-Sal send you. He'll ask a question about Atlantis. The answer can be found by read Plato's Lost Dialogue. Then ask him to come up to see Madame Sophia. Don't say that Madame Sophia wants to trade wisdom, or come up to see the greatest show. Just get him up to the hotel room. In the room, tell Sophia to keep him busy while you try something while they're talking. Open the cabinet under the mirror and get the flashlight. Get the bedsheet. Open the fuse box. Pull the circuit breaker. Lights out! Use the bedsheet; use the flashlight; use the mask. Trottier will run out of the room, leaving the Sunstone behind. Now go outside and use the taxi to fly back to Algiers. 
Don't worry if you come back empty handed. He'll ask you if you'd like to trade your mask for something. Say yes. Take the item Omar offers when he says something like red wagon, yellow scarf, etc. It's
the color that's important, not the item. And it changes from game to game. Just take the item and offer it to the grocer (he's outside to the left of the knife thrower). If the grocer tells you he won't accept gift for himself and not of this color, go back to Omar's and trade it for another item, but of DIFFERENT color this time. Keep trying items of different colors until the grocer says something like this is a pleasant color. Once you know the color he wants it's just a matter of picking the right item. Once the grocergives you the squab-on-a-stick, give it to the beggar and he'll let you have the balloon ticket. Go up to the roof and show the ticket to the balloon vendor. Get in the balloon. Once you're up in the air, cut the rope with the knife. 
You'll have to get Sophia out of the hole. Go down the ladder. Turn up you monitor's brightness and contrast if you're in the dark. Get the long rubbery thing (it's a hose). Get the clay thing (it's a jar) to the right of the track. Go back up to the truck. Use the hose with the gas tank; use the jar with the hose to get the gasoline. Go back down the ladder. Use the gas-filled jar with the metal cap. Turn on the portable generator. Now, pick up a ship rib. 
Use the rib on the crumbling wall to the right. Pick up the wooden peg on the table. Use it on the mural. Use Sunstone with peg in hole. Use the Sunstone. Look at Plato's Lost Dialogue to find out how align the stone. This changes from game to game! Sophia will come out if you align the stone correctly. She'll give you an amber fish on a string (orichalcum detector) and a distributor cap. Open up the generator. Turn if off and get the ceramic thing, which is the spark plug. Go back up to the truck. Stick spark plug and distributor cap in engine, and close the hood. Get in truck and go to Crete. 
Look at the stone to left of the horns; you'll see a statue; use the surveyor's instrument on it. Align the crosshair so that it points to the left tall horn. Click on the crosshair. You should see a dotted line shoot out with an"X" trailing it (if not, click a little to the left or a little to the right
when viewing through the instrument). Look at the stone to the right of the tall horns and do the same (when this doesn't work, click a little to the left or right on that horn, until it does work). The same thing should happen. You'll now see an "X" on the ground. Dig with the ship rib and get the Moonstone. Leave the dig site and go to the right. Use Sunstone and Moonstone on spindle. Consult Plato's Lost Dialogue for the proper alignment. If you can't figure out the alignment, there's no other way than trying all combinations(!) Go inside the Greater Colony of Atlantis.
