Basilisk II fits users maintaining older Macintosh applications and archives. Supply a compatible ROM and operating system, create a dedicated virtual disk, and test the application with a small copy of the original data.
A Macintosh ROM and Mac OS 7.x through 8.1 are required separately. It does not emulate PowerPC-only Macintosh software. Check compatibility with the target hardware and operating system before relying on it for everyday use.
