What's New

Note: This is the last planned version to support Windows XP.

  • [Change #1363] Right-click Disk Drive buttons QoL features to manage new disk images.
  • Support creation of new DOS/ProDOS blank or formatted disk (including default ProDOS apps).
  • [PR #1364] Document the new UI workflows.
  • [PR #1375] Document the disk image size magic numbers.
  • [Change #1365] Update disk images included with AppleWin distro.
  • [Change #438] Remove MASTER.DSK and add BLANK.DSK (created using the newly added DOS 3.3 System Master disk).
  • Add 'DOS 3.3 System Master - 680-0210-A.dsk'.
  • Add 'ProDOS_2_4_3.po'.
  • [Change #478] Support up to 16MiB in RamWorks III card (-r 256), and default to 1MiB (eg. -aux rw3, without -r switch)
  • [Change #1397] Debugger: Monitor's memcpy: Warn and abort when the source's end address is below the source's start address.
  • [Change #1384] Debugger: Support viewing pseudo-HGR pages at all multiple-of-8K physical start addresses within the 64K main memory.
  • [Change #1341] Support Apple //e with empty aux slot, or with a 1KiB 80-column card.
  • Includes accurately supporting the video modes, eg. aux=empty and enabling 80COL, then floating bus is fetched for aux memory.
  • Currently only available via the command line: -aux <empty|std80|ext80|rw3>.
  • NB. For -aux empty, -aux std80 and -alt-cpu-emu this uses a different CPU emulation code path, where full-speed runs 25% slower.
  • [Change #1403] Help window now owned by the desktop (instead of AppleWin window).
  • Change: Improve logging: for -fs-width/height=x: for each display resolution, after the WxH also output the aspect ratio.
  • [Bug #1402] Improve robustness of WOZ chunk processing, and reject image if it's malformed.
