KryoFlux is a USB-based floppy controller designed specifically for reliability, precision, and getting low-level reads suitable for software preservation. It's here, it's there and it's working - today. This is the original developed by The Software Preservation Society, the authority in authentic disk imaging and floppy disk preservation. SPS experts are industry veterans with more than 25 years of experience in computers and media archival, also including film restoration, transfer and archival. Chances are good you've used one of their applications (e.g. X-Copy and Cyclone) or played one of their games (e.g. Abandoned Places) in the past. Code designed by our engineers is being used in millions of industrial and consumer products, and if you've ever used a next-gen game console, chances are again good you've also already used it without ever noticing.

Main Features
  • Read at lowest level possible - precisely sampling the magnetic flux transition timing. Custom formats? Recording scheme violations? Encodings? KryoFlux reads them all!
  • Save as raw stream, or export to common sector formats supporting: Acorn Electron, Apple, Amstrad CPC, Archimedes, Atari 8-bit, Atari ST, BBC, Commodore 64, Commodore Amiga, MSX, IBM PC, PC-8801, Sam Coupe, Spectrum, E-MU Emulator & Emulator II, DEC RX01 & RX02 and many, many others.
  • Write back to disk. KryoFlux supports "one-click" writing of ADF, G64 and IPF files, with more formats in development.
  • Load raw dumps instantly in the emulator of your choice, e.g., but not limited to: WinUAE, FS-UAE, E-UAE, WinSTon, Hatari, STEem, Caprice and Spectaculator.
  • Parallel export support. E.g. An Amiga/ST dual format disk can be written as raw stream, an ADF and an ST file, all at the same time during a single disk capture.
  • Intelligent software allows production of sector images for virtually all normal disks for systems containing a generic FM or MFM floppy controller. Many other weird synthesiser sample disk formats should work right out of the box.
  • Reading and writing is completely independent of real drive speed, also supports variable rate "zoned CAV" disks (e.g. Apple) in a normal fixed rate drive.
  • RoHS and WEEE compliant.
  • High quality immersion gold coated boards, made to last a lifetime.
  • The de-facto standard for true disk imaging and preservation.
  • Already in use at many institutions around the globe, e.g.: Beinecke Rare Book & Manuscript Library, Yale University, USA; Bibliothèque nationale de France; Bodleian Libraries, Oxford, UK; Computerspielemuseum, Germany; Directorate of Scholarship and Collections, The British Library; International Center for the History of Electronic Games at The Strong, USA; The New York Public Library, USA.

Technical Specs
  • Compatible with USB 2.0 (high-speed).
  • Powered by USB interface (approx. 500mA). Drive requires its own power.
  • Shugart (with extensions) drive interface. 34-pin dual-row header connector.
  • Works with all major 3.5" and 5.25" drives, also works well with selected 3" (e.g. Amstrad FDI-1) and 8" (e.g. Shugart 851; might require additional adapter) drives; other types of drives and media currently under investigation.
  • Connection of two drives supported using a dual floppy cable, one can be accessed at a time.
Notes
  • Host software is currently Windows (XP, Vista, Windows 7 and 8 in 32 and 64-bit flavours), Mac OS X and Linux.
  • Open file format, DRAFT, used to store raw flux reversal timing information - in development.
  • Software completely free for private, non-commercial use.
  • Easy to use graphical user interface.
  • More details available here.
  • Please feel free to contact SPS here if you have any questions.

KryoFlux FREE for AmigaOS v3.7, imaging only, no writing

IPF decoder library v5.0, to load IPF and CT Raw files in the emulator of your choice


While you are here: try VICE 2.4a SPS (Windows) with enhanced G64 support to make use of your newly created G64 files. This version is sub-cycle exact and should work with all protections. It contains all our previous enhancements from VICE 2.3.20, some of which were left out of the 2.4a codebase for no apparent reason. This is the real deal that will play all true G64 files. If you want to compile it yourself, get the files that have been modified (same as for 2.3.20) and apply them to the original 2.4a source download.

Don't forget to download Defender Of The Crown for C64 and Bounty Bob Strikes Back for C64 as well to try the new features.
