Loading joystick settings from snapshots
Spectaculator saves both players' joystick settings and button mappings to zx-state files, along with the rest of the emulated Spectrum's state.

Sometimes it may be desirable not to restore these when re-loading the snapshot.

For example, in some tournaments such as Speccy Tour, the snapshots are provided by the competition organisers and thus contain the organiser's joystick configuration rather than yours.

To enable or disable loading of joystick settings from snapshots

On the Tools menu, click Options.
Click the Advanced tab.
Click Restore joystick settings from snapshots.
Click On or Off in the resulting dropdown list.
Click OK.
