!RollDemo/Technical
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.

File contents
Roll On is written in pure ARM code (except the desktop front end (which is written in good old BASIC)).
the main game consists of 21044 lines of ARM code.
It runs in mode 13 updating at 50Hz.
Sound is replayed at a frequency of 10KHz.
Will run unaltered on ARM2/ARM250 and ARM3 machines with RISC OS 2 or 3 and only requires 1Mb RAM.
It has 42 levels.
It was programmed on my A3010 (2Mb, ARM250, RISC OS 3.11) and I have tested it on an A3000 (2Mb, ARM2, RISC OS 2).
I haven't tested it on an ARM 3 machine but there's no reason why it shouldn't work, the wimpslot is only 640K so it should run OK on 1Mb machines.
Books used in this production:
Archimedes assembly language.
The RISC OS 3 Programmers reference manual.
A Beginner's Guide To Wimp Programming.
Thanks go to the authors of the above books.
Well that's about it from me. If you want to read some more garbage from me read the scrolly (Select 'Scrolly..." from the icon bar menu)
I hope you enjoy the game, if not the learn to program (if you can't already) and write something better.
