OSXII, an Apple //e emulator for Mac OS X utilizing Cocoa and OpenGL. The main purpose of this emulator is to run classic games, such as Wizardry or Ultima. OSXII is freeware and in order to use the emulator, you must supply your own ROM files and disk images.
This emulator has not been developed from scratch. It is based on previous work by David Empson, Randy Frank, Ben Koning, Doug Kwan and others. It uses and extents the functionality of a quite old emulator for Unix and X11 called YAE (Yet Another Apple Emulator).
