Basilisk II 1.0-Pre JIT R5 (01.May.2006)
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.
