I don't know how many would think this is worth the trouble but GameTap (part of Turner Broadcasting) is porting
a bunch of old arcade games to the Intel MAC platform:

Like Myst Online: Uru Live, GameTap for Mac utilizes Cider, the translation layer technology from TransGaming that enables games made for PCs to run on Intel-based Macs. Cider recently grabbed headlines as the technology opted by Electronic Arts (EA) to bring six of its hit game franchises to the Mac this summer, including Madden NFL 08, Need for Speed Carbon and Harry Potter and the Order of the Phoenix.
Cider only works on Intel Macs, but Sanchez said that otherwise it wouldn’t have been possible to develop a Mac version of GameTap.
