Applewin Apple II Emulator Updated

June 1, 2025

The Applewin Apple II Emulator has been updated. Version 1.30 release 21.0 includes a ton of changes, code refactoring and updates. Many of the updates included in this version are from Applewin contributors Audetto and Jamila’s. Updates items in this release of Applewin include:

[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.
[Bug #1383] Fix initial volume of Mockingboard card (and SSI263/SC01 devices) after loading a saved state. [@audetto]
[Bug #1372] Fix restoring SSI263 and SC01 continuous phoneme playback from save-state.
[Bug #1367] Fix for KeybReset() not called after a configuration reset.
[Bug #1360] Fix NMOS 6502 illegal opcode 0x0C (aka SKW).
[Bug #1359] DebugFont: use an ID which is a valid macro. [@audetto]
[Bug #1319] Fix SmartPort reading Status into aux memory (if aux banked in).
[Bug #1340] Fix AppleWin not able to switch to full-speed disk mode after playing a speech phoneme (regression at 1.30.19).
[Bug #290] Fix for very slow Pascal builds on a 128K machine – using new command line: -alt-cpu-emu.
[PR #1352] Add SoundBuffer interface. [@Jamiras]
[PR #1345, #1350, #1355, #1357, #1373, #1379, #1389, #1395, #1400] Much refactoring to the code by Andrea Odetti / @audetto.
