What happened to Emux.com?

Something that has bugged me for a couple of years now... anybody know what happened to Emux.com? It was one of the few sites that has the most extensive library of sega genesis games and besides that they had this cool feature where they used a shopping cart to assemble all the roms you wanted into one neat download list.
Talking about shopping cart... anybody know how to make it work so it lists files that users has added to their shopping cart and then let them download the files after visitors are done searching?
