The latest version of the Applesauce Floppy Disk Controller software has been released. Applesauce FDC version 1.56.1 includes the following updates:
Improvements and Fixes
- A new system has been created for processing hard-sectored disks. This will allow for the rapid implementation of support for new disk formats.
- Added another data repair technique for disks using IBM sector structure.
- Added DMK exporting for TRS-80 disks.
- Improved IMD exporting.
- Analog Chacteristics test has been revamped a bit to allow for drives with very tight filters to be able to run the test successfully. You can also now choose to run the tests while viewing head 0 and 1 (like existing) or against inner and outer tracks.
- Cleaned up reporting of bad sector checksums on Apple 3.5″ GCR disks.
- Apple II disks using standard sector structures will now log messages in the Disk Analyzer when they are using incorrect/invalid track/sector numbers.
- Fixed crash in FAT12 file system parsing that was triggered by an Atari ST copy protection. Yes, a 30 year old copy protection that tried to make disk copiers crash is still doing it’s job.
- Fixed logging of IBM sectors with a bad data checksum. It was sometimes using incorrect log messages.
- Fixed potential crash in Mac MFS file system parsing if the directory structure is corrupted.
Other Improvements and Fixes
- Improvments to flux reading that increase clock accuracy and prevent timebase decoupling for hard sectored disks with a high sector count.
