Changes:

  • SerDrive: Fixed a bug that prevented use of 3.5" 720 KB floppy disk images.
  • Also added support for Microsoft DMF (Distribution Media Format) floppy disk images.
  • XTIDECFG / Library: Minor size optimizations. Added a new macro (SKIP1B) as part of that.
  • BIOS: A small size optimization (2 bytes) to MODULE_8BIT_IDE_ADVANCED that is enabled only when USE_NEC_V is defined.
