!PlayerMod/UserBits/!Format

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.

|   Information about various Sound Tracker formats

---------------------------------------------------------------

There are now quite a few different file formats (some with the
same filetype !) for Sound Tracker songs, samples, etc.  I have
just had to work out !Tracker's simple sample format,  and this
is detailed  below.  I hope that others  will add  other format 
details (+correct wrong details !) in due course.

Please do not separate this file from its application !
