Showing/Hiding Crosshairs
MAME can display an aiming crosshair for each lightgun, even if a game did not
originally have one. It is personal preference whether you leave them on or turn them
off.
To change the crosshair setting in MAME:
1) Press the Tab key (default key) to bring up the MAME Config Menu
2) Use the Up/Down arrows (or joystick) to move the selection, and press the Enter
key (default key) to select Crosshair Options.
NOTE: This menu item will only appear for guns recognized by MAME as lightgun
games.
3) Change the setting by selecting P1 Visibility.
Auto: The crosshair is on when being moved, and will disappear after the time
set in the Visible Delay.
On: The crosshair is on all the time.
Off: The crosshair is off all the time.
Each player (if the game allows more than one simultaneous player) has their
own crosshair setting. These settings will be saved for this game, and may be set
independently for other lightgun games.
