DAPHNE LaserDisc

DAPHNE is the First Ever Multiple Arcade Laserdisc Emulator!1) For legacy reasons, the Hypseus fork of the emulator may be referred to as simply DAPHNE.

A LaserDisc video game is an arcade game that uses pre-recorded video (either live-action or animation) played from a LaserDisc. The first LaserDisc video game was Sega's Astron Belt released in 1983. The genre was popularized by Dragon's Lair released shortly after in the same year. The usage of LaserDiscs provided graphics close to an animated or live-action film which was vastly ahead of other arcade games at the time. However, with the drawback of limited interactivity compared to regular arcade games.

This system scrapes metadata for the daphne, arcade group(s) and loads the daphne set from the currently selected theme, if available.

  • Emulator: DAPHNE/Hypseus
  • Folder: /userdata/roms/daphne
  • Accepted ROM formats: .daphne .squashfs

No Daphne emulator in Batocera needs a BIOS file to run.

Place your DAPHNE ROMs in /userdata/roms/daphne/.

The file structure consists of a directory with the ending .daphne and a corresponding .zip file in the folder roms:

|-- daphne
|    |   (The folder below holds a laserdisc...".daphne"
|    |   tells emulationstation to add this to the menu,
|    |   and "dle21" tells daphne to use that game engine)
|    |
|    |-- dle21.daphne     
|    |    |-- dle21.commands  (Optional extra command-
|    |    |                   line params!)
|    |    |-- dle21.txt      (Framefile)
|    |    |-- lair.m2v
|    |    |-- lair.ogg
|    |
|    |                (All roms go into this roms folder)
|    +-- roms
|         +-- dle21.zip

Without the additional .zip file in the roms folder the games will be recognized by Batocera but will not be playable!

DAPHNE is the most famous emulator for LaserDisc arcade games. It supports more games than MAME. We use the Hypseus Singe, a fork of the original DAPHNE emulator.
