Yet another noob with a problem

[Elbo444]

So I get the usual "cannot find 1_01d_01.bin in romset dc"

But I HAVE dc.zip with 1_01d_01.bin in it, in the same folder, why can't DEmul find it?

Make sure that you've actually set the rompath in Demul's settings, and that the CRC and hashes of the BIOS file match to what's written in dc.dat.
