Basilisk II

Basilisk II is an emulator which emulates Apple Macintosh computers based on the Motorola 68000 series. The software is cross-platform and can be used on a variety of operating systems.
Christian Bauer (developer of a Mac 68k emulator ShapeShifter for Amiga) released the first version of Basilisk II in March 1999. New emulator should be highly portable across several computing platforms and provided some improvements in comparison to ShapeShifter - e.g. no limit for number of emulated disks, improved CD-ROM support and support for the host file system. However, early reviews highlighted several issues like difficult configuration and limited compatibility with recommendation of ShapeShifter as a better choice for Amiga users. Newer releases mitigated these problems, 2005 review of the MorphOS version noted only slow CPU emulation (in comparison to built-in 68k CPU emulation for Amiga applications in MorphOS) as a major issue.
The latest version of Mac OS that can be run within Basilisk II is Mac OS 8.1, the last 680x0-compatible version. Newer Mac OS versions are incompatible because they require a PowerPC-based processor, which Basilisk II cannot emulate.
Ports of Basilisk II exist for multiple computing platforms, including AmigaOS 4, BeOS, Linux, Amiga, Windows NT, Mac OS X, MorphOS and mobile devices such as the PlayStation Portable.
