PD/SprShift/!SprShift/history
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.

Editors and Impression savers are for squares Aswell :-> --> <title>SprShift - History and other stuff</title> </head> <body> <h2>History</h2> <dl> <dt>v0.00 (16/1/96)<dd>Woke up Sunday morning and this seemed a good distraction from the mother of all hangovers. Actually, going back to the pub seemed a good distraction, but had to kill a few hours before they opened. Developed into a testbed for various ideas (witness this page) as well as a way of getting to know RiscOS C and the toolbox. <dt>v0.90 (8/3/96)<dd>Tarted up and send to AU Ed as a submission </dl> <h2 id="limits">Limitations</h2> <ul> <li>All sprites which do not have an even number of pixels across and down will be skipped. Pure algorithmic laziness on my part... <li>Requires the toolbox to run. While my prime reason was again laziness I still think this is a good thing. <li>Could probably be faster/more efficient <li>umm, other stuff.. Users are the best people to stumble over cockups anyway. </ul> <hr><address>© Mike Dickens, 1996</address><img src="sig"> </body> </html>
