physical disk, or an ISO file?

[NavyGunner1980]

Hi, I have purchased Dragon Lair and Space Ace on both the Amiga platforms and would like to purchase copies to put in an arcade cabinet that I am building using the MAME or Daphne emulator, I tried using daphne and my window 95 Dragons Lair Deluxe CD, but I get a message saying something to the effect the 'the disk is not eligible' can you please point me to somewhere I can buy either the physical disk, or an ISO file?
I emailed digital leisure and asked where I can purchase a physical copy and they directed me to their website where they say "Unfortunately, physical copies of the Dragon's Lair series are no longer available. However, you can find digital copies for download on all major platforms if you want to play!" and "Unfortunately, physical copies of the American Laser Games series are no longer available. However, you can find digital copies on the PSN store if you want to play some of your favourites!"

Thanks

Are you trying to play the Amiga version or the actual laserdisc version?
