Basilisk II JIT

Basilisk II is an Open Source 680×0 Macintosh emulator developed by Christian Bauer. That is, it enables you to run 68k MacOS software on your computer, even if you are using a different operating system. However, you still need a copy of MacOS and a Macintosh ROM image to use this program. Basilisk II is distributed under the terms of the GNU General Public License (GPL).

The Basilisk II JIT project aims at improving the run-time performance of the emulator. In technical terms, it uses dynamic recompilation techniques to translate original 680×0 code into native code (currently x86 and x86_64). The engine is derived from Bernie Meyer's just-in-time (JIT) compiler engine for UAE. Further bug-fixes and improvements were made for Basilisk II.

The following platforms are currently supported: Linux/i386, Linux/x86_64, FreeBSD/i386 and MacOS X for Intel. An experimental port to Windows is available again but it's still looking for proper maintainership.

Note: This webspace contains development code currently available in CVS. Though efforts are made to ensure stability, regressions are possible. Please see the Official Basilisk II Homepage for stable builds.

Features

  • Emulates either a Mac Classic (which runs MacOS 0.x thru 7.5) or a Mac II series machine (which runs MacOS 7.x, 8.0 and 8.1), depending on the ROM being used
  • Uses UAE 68k emulation or (under AmigaOS and NetBSD/m68k) real 68k processor
  • High performance JIT translation engine for x86 and x86_64 (AMD64, EM64T)
  • Copy and paste of text between MacOS and the host OS
  • Easy file exchange with the host OS via a “Host Directory Tree” icon on the Mac desktop
  • Color video display with support for run-time resolution switching
  • CD quality sound output
  • Floppy disk driver (only 1.44MB disks supported)
  • Driver for HFS partitions and hardfiles
  • CD-ROM driver with basic audio functions
  • Ethernet driver
