- MZX version 1.10
- =================
-
- Instructions for Use
- ====================
-
-
-
-
- Loading
- -------
-
- To load MZX, double click on the !MZX icon. This will install the MZX icon
- onto the icon bar. Alternatively, click on a file of type SNA (&CEF) or
- Z80 (&CEE). This will also install the icon bar icon, but will pre-load
- the snapshot file.
-
-
- Starting
- --------
-
- To start up the emulation, click on the MZX icon bar icon. Clicking with
- Select will open a multitasking MZX window; clicking with Adjust will
- switch to single task mode. Note that single tasking may not be possible
- at present with some monitor types; normal (TV 50Hz) monitors and
- multiscan monitors should be able to cope. In addition, attempting to
- select single tasking mode will crash a Risc PC 600.
-
-
- Changing between modes
- ----------------------
-
- In multitasking mode, clicking Adjust on the icon bar icon will switch to
- single task mode. (Clicking with Select will always open the MZX emulation
- window.) In single tasking mode, you can return to the desktop by pressing
- Alt-F1. In multitasking mode, clicking Select in the emulation window will
- gain the Input focus, allowing keys to be interpreted as Spectrum
- keypresses.
-
-
- Loading a snapshot
- ------------------
-
- At any time after starting the emulator, you may load a snapshot file of
- type SNA or Z80 by either dragging its icon to the icon bar icon, or by
- dragging it into the !MZX emulation window.
-
-
- Options
- -------
-
- The Options dialogue box is obtained from the MZX menu. The options are:
-
- Sound: Switch sound on/off. (Note that sound does not work on newer
- machines thanks to Acorn's cost-cutting, and it also incurs
- a slight speed penalty.) Sound is only available in single
- task mode.
-
- Speed Control: Enable/disable speed limiting. This is useful on ARM3
- machines where the emulation runs too fast. Note that it
- is only active in single tasking mode, and can disrupt
- the sound output.
-
- Freeze: This option pauses the emulator. It is automatically
- switched on when you close the MZX emulation window.
-
- Acorn Joystick: This switches between keyboard joystick emulation (keypad
- keys 1-4 and Enter behave as a Kempston joystick) to real
- joystick emulation (Acorn-compatible joystick behaves as
- a Kempston joystick).
-
- Loading: This is the amount by which the speed control option slows
- down the emulation in single-tasking mode, and is selectable
- from 1-255.
-
- Refresh: This is the number of frames between window redraw in
- multitasking mode. The higher the value, the faster the
- emulation will run, but high values also make the display
- appear jerky and unresponsive.
-
- Diagnostics: Enable/disable diagnostic printing. This may provide
- explanations as to why a snapshot file fails to work. It
- should be left off in normal use.
-
- Note that these options have associated key-combinations:
-
- Freeze: Alt-F9
- Unfreeze: F10
- Sound on: Alt-F5
- Sound off: Alt-F6
- Increase loading: Alt-F4
- Decrease loading: Alt-F3
-
- Volume up: Alt-F8
- Volume down: Alt-F7
-
-
- Saving snapshots
- ----------------
-
- Pressing Alt-F2 will save a snapshot to the file <snapshot$file>. Use
-
- *set snapshot$file <filename>
-
- to specify where you want the file saved; the default is a file 'SnapShot'
- in the same directory as MZX. (Drag save will be implemented in the next
- release.)
-
-
- Quitting
- --------
-
- Select Quit from the MZX menu, or press Alt-Q.
-
-
- Reset
- -----
-
- Pressing Alt-R has the same effect as the Spectrum 48+ reset button.
