IPF Library Source Code Released [New!]

It's taken a long time, and we really appreciate your patience. We have finally released the IPF library source code, under the same terms as MAME (non-commercial use). Other licenses may follow. This code also includes a cycle exact, low level WD177x emulator that works at the signal (not command) level. (more)

Duplicator Info (DI)

With C64 support around the corner, people are actually wondering why titles should be redumped, with several other projects already dumping C64 disks. Commercial games were usually copied at replicators that used many automated machines for high volume output. Such machines were produced by several companies with Trace Products (today: Trace Digital) being the largest with an estimated 80% market share. (more)

Commodore 64 (C64) Preservation - we need your disks!

10 years ago, SPS (known as CAPS) started work on preserving Commodore Amiga disk images. Since then we've moved on to cover other less exotic disk platforms such as Atari ST, ZX Spectrum and more. Just as challenging as the Amiga, and just as close to our heart, and long overdue is the classic, Commodore 64. (more)

KryoFlux Write Support (now in final testing)

Broken original game? Used a virus scanner to replace the allegedly dangerous non-standard bootblock? Bought it from eBay just to find out it was "fixed" by copying a crack over it? Very exciting news! We are now in the final stages of testing the new write support in KryoFlux. Finally, we are able to restore our game disks and continue to play them on real machines after our originals have worn out. (more)

KryoFlux Track Data Visualisation

Over the last few months, aside from the work on writing support for KryoFlux, we have been working on providing more insight into disk data by means of data visualisation, since this is often helpful in identifying the cause of errors and provides useful information about the disk encoding.

Making IPF Open......

We've always said we intended to make IPF an open format, and that we would do so when we felt that we, and the format, were ready. It's taken longer than we had hoped, as these things do, but we feel the time is now right. We now have to decide what license to use, and we thought it best to have an open discussion between us, and you guys from all viewpoints, to come up with something that we can hopefully all be happy with.

CPC Emulator supporting IPF

For quite some time IPF was Amiga exclusive. Not so any more! We have hundreds of IPFs created for other platforms, and all of them were tested either under emulation or using the HxC device on a real machine. We'll shortly add links to the download page where you can find an emulator that supports the use of IPF files listed by platform. Most recent is a re-release of Ulrich Doewich's Amstrad CPC emulator 'http:sites.googl (more)

KryoFlux - Write support is here and coming to you!

We're closing the circle and we're wearing our roller skates. After nearly ten years of preserving software and getting it off the media, we're ready to write it back – thanks to KryoFlux even more precise and pristine than possible in the 1980s and 90s. (more)

E-MU Systems Emulator II disk format uncovered

About 26 years after the debut of the most popular sampler of the 1980s Softpres specialist István Fábián uncovers the details of the disk format used by the Emulator II. Used by artists and bands like Jean-Michel Jarre, Depeche Mode, Pet Shop Boys, Vangelis and Enigma, the very distinct sound of the machine became a common ingredient for many hit singles until the early 90s.

Multi Platform Effort Is Go!

Our previous post on multi-platform support introduced eight games not exclusively for the Amiga preserved. All of these were either ST/Amiga or PC/Amiga dual-format, which was a neat, if rather modest, start. Today, we are very pleased to announce the first real batch of preserved disk-based games for systems other than the Amiga, namely the Atari ST, Amstrad CPC and Spectrum. (more)

Multi Platform Support

As of today, The Software Preservation Society is proud to announce that we have finished implementing support for platforms using generic MFM controllers. Among the new platforms supported are Atari ST and IBM PC, and even dual or triple format disks, where the game for more than one platform exists on the very same disk. (more)
