Windows Frotz 1.28 was released on 1st April 2026.
- Windows Frotz now automatically applies a collection of patches for various problems in the Infocom games Arthur, Beyond Zork, Bureaucracy, Journey, Sherlock, Stationfall and Wishbringer. These patches were taken from Chris Spiegel's Z-code interpreter Bocfel. The patch for Arthur replaces the changes made in 1.22 to limit the size of the window when playing Arthur.
- An anti-aliasing algorithm is now used when rescaling the Infocom V6 graphics. This allows Windows Frotz to use a window size based on the screen size for Infocom's V6 games, adjusted to have the correct aspect ratio to match the original presentation of these games.
The screen modes used by Infocom's MS-DOS V6 interpreters have non-square pixels with relative dimensions of 5:6, i.e. 20% taller than wide. This is now simulated by stretching the height of images and the window by 20% when playing an Infocom V6 game with the interpreter number set to MSDOS. - The release 242 beta versions of Zork Zero require different implementations of the get_wind_prop and put_wind_prop opcodes, which are now implemented as special cases for these versions.
- Ctrl+Backspace now deletes the word to the left of the cursor.
- Ctrl+K and Ctrl+W now copy the input text that they remove to the clipboard.
