This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

!PNG2SPR Version History V1.0 17 Dec 95 This version is based on release 0.85 of the PNG spec. It implements the basic (i.e. compulsory) chunk types, and uses the "Title" keyword to give the window a title. It does not implement the Alpha channel, it just ignores this. It only works under RiscOS 3.5. V1.01 30 Dec 95 Better set of sprites for low res modes. Sprites now match official PNG sprites. Corrected my email address in help file :-(. Now deals with arbitrary length chunks. 16bpp greyscales currently produce some inspiring effects (rather than crashing as previously). (i.e. they come out funny colours). Implemented gamma correction (using file gamma only) Fixed bug which occured if 1st line of pic was not filter type 0 or 1 (i.e. it referred to a non-existant previous line). v1.10 11 Sept 96 Rewritten in C using the PNG & ZLib reference libraries, and the Acorn Toolbox. Supports multiple images, all with individual %age hourglasses. 16bpp greyscales now work. "Iconise" with standard pinboard works properly. Works under RISCOS pre 3.5 (I hope). v1.11 21 Sept 96 Fixed bug to do with memory not being zeroised, causing corrupt sprite names & psychedelic pallettes on Risc PCs. Added a small info window that says it hasn't been written yet. v.12 22 Sept 96 Corrupting interlaced files when < 8 bits per character. Oogh. 32 bpp files not working with !Paint on StrongArm - new version doesn't like a right hand bit > 31 (!). Added transparency configuration. v1.13 29 Dec 96 Corrected tRNS handling for greyscale images. Added a configuration option for greyscale backgrounds. 16 & 8 bit greyscales with masks get transformed to RGB pics, as it's currently the only sensible way I can deal with them. v1.14 25 Jan 97 Running with LibPng 0.90 v1.20 1 Mar 97 First version to convert sprite files to PNG files. Just drop a sprite onto the iconbar icon & drag the save box to where you will. v1.21 28th July 97 Deals more cleanly with mega large images. calloc() falls over if you give it an excessive "size" argument :-(. Running with LibPng 0.96. 16 & 8 bit greyscales with transparency chunks and masks now work properly, and remain the correct colour type! Fixed obscure bug with gamma corrections on gray scale images. Fixed bug in handling pHYs aspect ratios. v1.22 21st September 1997 Improved memory handling for strings & things. Fixed memory leak on writing due to bug in libpng. Deal with masks when converting sprites to PNG files for all but 8pp images. Get correct palette for images using Wimp palette. Fixed bug when creating 32bpp masks. Clears supremacy bits on 32bpp pictures. v1.23 9th November 1997 Uses Virtual Memory if Virtualise loaded. Chronic bug decoding masks for 32bpp pictures. Fixed some bugs dealing with decoding backgrounds - bug in libpng. File system errors no longer fatal - note that this may cause problems if you close a file which is being decoded...
