Laserdiscs were predecessors to the DVD. The first laserdisc game was released in 1982. Laserdisc games function much like interactive fiction where you choose your own story and the video adapts to the path you choose to take.

Default dapinput.ini

# Daphne cutom keyboard and joystick mapping
#
# Each input is mapped to 2 keyboard keys and one joystick button.
# A joystick's first analog stick is also automatically mapped.
#
# The first two numbers are SDL keyboard codes (or 0 for "none")
# Find keyboard codes here:
# http://www.daphne-emu.com/mediawiki/index.php/KeyList
#
# The third number is the joystick button code (or 0 for "none")
# Since 0 is reserved for special meaning, joystick button 0 is identified
# as 1 here.  Button 1 is identified as 2, and so on.
# 
# Find the button you want to map by running:
# jstest /dev/input/js0

Troubleshooting

If you have issues with black screen, try deleting the .dat file as it is generated the first time you parse the video files. If you transferred the .dat file from another system it may not work, so just leave the .dat file out.

It is also case sensitive so if it's not working try making the extensions in the .daphne file lowercase.
