Docs/Scripts
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
6502Em: BBC Script files ======================== These are files intended to be the !Run file of an application directory containing a BBC game. When the application is run, !6502Em will be loaded if necessary (so long as it has been 'seen' by the filer). Within the script file, you can alter certain features of the emulator and specify which file to run first to load the game. The emulator's internal Currently Selected Directory (CSD) will be set to the directory containing the script file. The first line of the file MUST be: BBC Script On later lines, you may use the following commands: Palette [On|Off] Sound [On|Off] Patch [Off|<patchname>] Machine <machinename> TapeFile <filename> IndexFile <filename> Keymap [Default|<keymapname>] DisableTape ScrollHack LoadROM <filename> LoadRAM <filename> KillROM <ROMName> where: <patchname> is the name of a 'Patch' in !6502Em.Patches, <keymapname> is the name of a 'Keymap' in !6502Em.Keymaps, <machinename> is one of BBCB, Master128, Compact IndexFile takes a file containing names of files (in order) that will be loaded when a CHAIN"" or *RUN"" is issued (in the same directory as the Script) The last line of the script is then used to determine how to run the game. If the last line is non-existent, then the emulator will try to load a file of the same name as the application directory. If the last line is just a single word, then the emulator will try to load a file of this name. In both these cases, the emulator will try to work out whether the file is BASIC from its execution address or filetype. (&801F, &8023, &802B, &80E7 are executions addresses recognised) Otherwise it will be *Run'ed If it is recognised as BASIC from its execution address, page will be set to its load address before it is loaded. If the last line contains a space (ie is not a single word) or starts with CHAIN or * then that line will be typed into BASIC by the emulator. eg to turn the sound off, the last line might be: OSCLI "FX210,1" : *Run GameObj Some example Scripts: BBC Script BBC Script Patch Off Keymap Arcadians BBC Script Palette Off ExileL BBC Script Machine BBCB Patch Elite Palette Off Elite BBC Script Machine Master128 Patch M128Elite Palette Off MODE2 : */M128Elt BBC Script Patch Off Palette On PAGE=&1900 : OSCLI "FX210,1" : LOAD "LISTING" BBC Script TapeFile JSW Machine BBCB OSCLI "TAPE" : CHAIN ""
