- 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
