The initial alpha release of Basilisk II (for the Linux platform) was made on January 23, 1999 by Christian Bauer, who previously developed Frodo, a popular Commodore 64 emulator, Shapeshifter, a (obsolete) Macintosh emulator for the Amiga, and Basilisk, a (obsolete) Macintosh emulator for BeOS and Linux. The Windows port of the emulator was developed by Lauri Pesonen. At that time it competed with two commercial emulators: Microcode Solutions' Fusion and Emulators, Inc.'s SoftMac.

Later development was lead by Gwenole Beauchesne (site offline).

Beauchesne suspended his development of Basilisk II in April, 2008. Volunteers have contributed bug-fixes since then. Builds based on these fixes are listed here and in the Basilisk II forum.
