The roms of [mame.dk] was removed 3 days ago. [mame.dk] has received 
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.
