From Richard Bannister:
Modeler is a Sega arcade emulator for Macintosh. The current version supports the three Sega arcade boards based on the NEC V60 CPU - Sega System 32, Sega System 32 Multi, and Sega Model 1. While the Model 1 games are currently not playable, due to the lack of 3D graphics emulation, the System 32 games work quite well. Titles such as Golden Axe 2 and Spiderman are fully playable, provided you have a fast enough Mac.
