. .dsk / .nib images . ProDOS format / DOS 3.3 init . authentic / enhanced disk access speed For zero-length files, resize to the complete file size when first opened (#506) . Support both .dsk and .nib Created a new class FormatTrack to encapsulate the new track formatting logic Improved precision of 'authentic' drive mode's spin emulation (#125) Save-state: (save-state DiskII unit v2) . support Format Track state . save DiskLastCycle DenibblizeTrack(): added some debug asserts and comments Updated for VS2008/VS2013/2015/2017 projs & remove dependency on ddraw.lib for VS2013/2015 Updated disk logging: . Moved all LOG_DISK_xx macros to new DiskLog.h (since shared by Disk.cpp and DiskFormatTrack.cpp) . For write nibble: option to log cycle count & sync byte count . For written track: option to log gap1/2/3 and track size . For disk latch r/w: option to log when D5AA96 detected Other: . Debugger: Fix CD cmd to support absolute paths (#505)
