Clip from my Atari Dragon's lair. The machine is running with a modified ROM U45 to use Software Corner laserdiscs instead of original Philips ones.

  • i was wondering what's the difference between Software LD and Philips LD? very instering!

  • Software Corner LDG discs are copies of the original Philips ones. The disc content is almost the same, there's just a difference in the slides at the beginning of the disc. In the LDG ones they removed the slides related to faults in the arcade pcb. The animated footage is exactly the same, there's just a frame offset, so the original ROM has to be modified to take into account this offset in game searches.
