How to play Shining Force III: 3rd Scenario on Mac

Scenario 3, Bulzome Rising, stars Julian, a mercenary who appears as a secondary character in both Scenario 1 and Scenario 2. He is for all intents and purposes the true main character of Shining Force III. His initial motivation as the story begins is to track down and kill Galm, one of, if not the, most powerful member of the Vandals, a powerful race of beings that existed over 1,000 years ago. Julian believes that Galm killed his father and is seeking revenge. This story arc is first introduced in an earlier Shining game, Shining the Holy Ark, in which Julian appears as a young boy who asks the party to search for his missing father. Julian joins Synbios in the midst of his quest in Scenario 1, but after an encounter with Galm, he is tossed over a waterfall at the suspension bridge and believed by Synbios' army to be dead. He reappears in Scenario 2, apparently washing ashore at the site of a battle between Medion's army and the Bulzome Sect. Knowing the sect's ties to the Vandals, Julian agrees to fight alongside Medion. As it becomes clear that the sect is trying to kill Gracia, a child intended to become the next Innovator (A Shining Series figure equatable to a god), Julian takes on the task of protecting him and helping him realize his destiny. Scenario 3 starts about 60% through scenario 2's story, and focuses primarily on battles against the Bulzome Sect and their allies in both Aspinia and Destonia. While scenarios 1 & 2 happen at roughly the same time, much of scenario 3 takes place after both, but there is some "overlap". Eventually Julian leads a three-party coalition consisting of the armies of both Synbios and Medion, to engage in the final conflict against Bulzome, a powerful Vandal long sealed in another dimension, and the true orchestrator of the conflict.
