After a short public testing period, Andy McFadden has put the final touches on the indispensable toolkit CiderPress 4.0. Andy’s announcement is attached.

CiderPress, the Apple II disk and archive utility for Windows, has been updated for the first time in several years. An installer for Windows can be downloaded from

The last official release, v3.0.1, came out six years ago. A summary of the changes made since that release follows.

** New Features **

  • Support for viewing and extracting the contents of AppleSingle files.

** UI and Usability **

  • When opening files, CiderPress no longer restricts you to a specific type of file (ShrinkIt archive, ACU archive, disk image, etc.). Just open the file and CiderPress will figure it out.
  • The custom file+folder selection dialog, used when adding files, has been rewritten. The long-absent “Accept” button has been restored, and the newer style of dialog is easier to use.
  • The custom folder-selection dialog, used when selecting the folder to extract files to, has been replaced with a much nicer standard system dialog.
  • The font used in all dialogs has been updated to take advantage of ClearType.
  • Help files have been migrated from WinHelp to HtmlHelp, so it is no longer necessary to download the WinHelp viewer on Windows 7 and later.
  • Non-ASCII characters in the Mac OS Roman set — used for HFS filenames and IIgs documents — are converted to Unicode in the file list, file viewer, and many dialogs.

** Bug Fixes **

  • Corrected the default size of the file viewer, and the initial position when viewing tall SHR images.
  • Teach and AWGS conversions now handle “shadow” and “outline” (though you need to open the converted file in something like Word to actually see it). Applesoft listings with carriage returns embedded in REM statements now match LIST output.
  • Fixed the 640-mode palette offsets in the SHR converter. (This was actually fixed a year ago by Bill Buckels, and available in v3.0.2-d1, but the patch wasn’t part of an “official” release until now.)
  • Expanded Gutenberg disk support to include Gutenberg, Jr disks.
  • DiskCopy images with resource forks (e.g. on the ByteWorks Opus ][ CD-ROM) now open with double-click.
  • File type associations, i.e. what makes it so you can double-click a file and have CiderPress open it, started breaking a bit with permission changes in WinVista. This has been fixed, but not perfectly.

** Internal changes **

  • Moved from a CVS repository on sourceforge to a git repository on github.
  • Registered and moved the web site to it (now served up by github).
  • Updated the build files, which were originally set up for Visual Studio 6 (which dates back to 1998). It now builds cleanly “out of the box” with Visual Studio 2013.
  • Switched from _MBCS (narrow strings) to _UNICODE (wide strings). This affected all strings used in the user interface and in file names. The NuFX and disk image libraries still primarily use narrow strings, because they also build for Linux, but the Windows-specific parts are fully converted.
  • The help file “source code”, which used to be stored in a proprietary format, is now just plain text and HTML files.
  • Made various global changes to the source code, such as converting tabs to spaces, switching to variadic macros for debug log messages, and replacing vague C types like “unsigned short” with explicit types like “uint16_t”.
  • Fixed the Linux build, which had suffered from bit rot.
  • Updated to the latest version of DeployMaster (which creates the installer).
  • Expanded and updated developer documentation.

The net effect of all these changes is an application that looks a bit better, works a bit better, and will be much easier to patch and update in the future.

The newer build tools don’t support WinXP by default, but can be configured to do so. This required a few extra megabytes of DLLs in the installer. Earlier versions of Windows, such as Win2K and Win98, will not be able to run this or future versions of CiderPress. For those systems, version 3.0.1 should continue to be used.

Coincidentally, version 3.0.0 of NuLib2 has been released. The update was primarily a code refresh, with build fixes for Mac OS X, Win32, and Linux, but also added support for Mac OS Roman filenames on Linux and Mac OS. No meaningful change for Win32, though being built with the VS2013 compiler means the executable won’t work on older versions of Windows. Visit for more information.
