This great resource for mame roms removed all roms after recieving a notice from a copyright holder.
Here"s what it says on the site:
"The roms of [mame.dk] was removed 3 days ago. [mame.dk] has recieved a notice from a copyright holder forcing us to shut down our service.
We are sorry for keeping you in the dark for a few days, but we used the weekend to discuss how to handle this sad incident, trying to develop new ideas on how to provide our old service. The conclusion is unfortunatly: no rom downloads.
[mame.dk] is a hobby project, and we do not want to put our personal economy in jeopardy on this, and we do NOT want to go into legal matters. The [mame.dk] project has grown rather large lately, and despite many and generous donations, we had to throw in the banners to pay for bandwidth costs at the last release. So maybe we just got too popular.
We will continue to provide the database services at [mame.dk], as well as the supporting files (emulator mirror, screenshots, artwork, samples etc.), and we will consider adding new "features" to the system.
Kind regards, the [mame.dk] team
Bombjack, Mr.Do and DigDug"
