Automatically switch to HD data rate when reading from an HD disk #438

Open gardners opened 3 years ago

gardners commented 3 years ago

Currently it is upto the DOS to work out when a disk is DD or HD formatted, which it currently knows nothing about.

It would be desirable to automatically read HD disks when set to DD, so that software can easily be released on HD disks, that will still work with the C65 DOS to get a directory and load the loader etc.

This would ideally be done by adding a parallel 2x FDC MFM decoder.

This is probably currently disabled because focus was to be able to handle DD in release bitstream.

... and should stay open because of that :)
