!6502Em/Docs/Snapshots
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.

6502Em: Filetype BBCSnap (&BBC)
===============================
Acorn's filetype &BBC (BBC ROM) has been extended by 6502Em
If the first line of the file is one of the following:
BBC Script
BBC Tapefile
BBC Snapshot
BBC Snapshot101
then it is a new type of file, otherwise it is still
a sideways ROM image (which 6502Em will also load)
BBC Snapshot files are saved out by the emulator, and
contain the complete state of the emulator at the moment
it was saved.
BBC Tapefile files can be accessed from the emulator using
the casette filing system (selected by *TAPE)
BBC Script files are described in 'Scripts'
File format of 'BBC Tapefile'
-----------------------------
FF 04 : DCD bit goes high (ie data carrier STOPs and interrupt occurs)
FF 00 : DCD bit goes low (ie data carrier STARTs and NO interrupt)
FF FF : FF byte from tape hardware
nn : (not FF) byte from tape hardware
File format of 'BBC Snapshot101'
--------------------------------
NB if a location is "unused", any information in it will be discarded
when the snapshot is loaded. The information saved out is included for
completeness.
