depends, it's the old shop bought one from ages ago? has nothing to do with any of the x2 discs..
on the cd , how is it ? an installer "exe" or just 2 sets of folders ? I had the download version without any installer from DSF , so maybe it differs.. if it's got an installer on the EMU disks run that ?
Regarding additional content... whoever compiled the x1 disks made a slight error as it did include the DSF EMU programs but *NOT* the samples for them... the programs/patches shouldn't have been in there. maybe they did the same with x2 disks ,someone asked about it recently, with regard to x1.
