a Mini vMac Extra


cnvtdc42-1.0.0.zip (info) a zipped hfs disk image and checksum file. The disk image can be mounted with Mini vMac. Includes source code.

CnvtDC42 is an application to use in Mini vMac (version 3.0.0 or later) to convert disk image files created by Disk Copy 4.2 into the simpler format preferred by Mini vMac (discarding tags, checksums, and header, leaving just the raw image data).

This is useful because, as of version 3.2.2, Mini vMac by default only allows read access to Disk Copy 4.2 images. CnvtDC42 can be used to convert a Disk Copy 4.2 image into a format that Mini vMac can both read and write. (Previous versions of Mini vMac allowed write access, but didn't support the tags and checksums, resulting in an invalid image. Full read/write support, with tags and checksums, is now a compile time option.)

A new image file is created, and the old one is not changed. The old and new images are on the host computer, not the emulated one. So CnvtDC42 combines characteristics of both ImportFl and ExportFl.

See the Compiling page for instructions on compiling CnvtDC42 from the source code.
