Windows Frotz TTS 2002 is a modified version of Windows Frotz 2002 1.04, by David Kinder. 99.9% of this code is from the original. There have been about 50 to 60 lines of code added to support SAPI 5.1.

Windows Frotz 2002 was written by David Kinder, based on Frotz 2.42. Frotz versions up to 2.32 were written by Stefan Jokisch, who then handed the project on to Jim Dunleavy, who released Frotz 2.40. David Griffith released Unix Frotz 2.41 and 2.42 based on this. As well as adding a Windows interface, I have extended the Frotz 2.42 core to support menus and to use Unicode for characters throughout.

Some source code and many useful ideas have been taken from Kevin Bracey's Acorn RISC OS interpreter Zip 2000. Use has also been made of the source code for WinFrotz by Rich Lawrence.

Windows Frotz 2002 was translated into German by Lothar May, into Italian by Tommaso Caldarola, and into Spanish by Javier San José.

Windows Frotz 2002 uses jpeglib by the Independent JPEG Group; libpng by Guy Eric Schalnat, Andreas Dilger, Glenn Randers-Pehrson, and others; zlib by Jean-loup Gailly and Mark Adler; and ModPlug by Olivier Lapicque.

This interpreter would not have been possible without those who have worked to understand and document the Z-Machine in all its various forms: The InfoTaskForce (David Beazley, George Janczuk, Peter Lisle, Russell Hoare and Chris Tham), Matthias Pfaller, Mike Threepoint, Mark Howell, Paul David Doherty, Stefan Jokisch, Graham Nelson, and many others.
