I won against Darkello on 6LM10 in 141 turns, but I'm a bit hesitant to post it, because Darkello immediately asked for the password (for those who know about their game with Sonic)).
He wasn't lucky; Sinimu, as always, got a one-sided map, and the treasure chests were bad. One was purely for experience, and the other was a sand treasure, so he couldn't find enough money throughout the game.
