I've tried running darkstalkers on both mame and nebula, and both give me an error saying the files cannot be found. I've downloaded the zip file from here and extracted the files into the rom directory for both of them. Here's a list of the files I downloaded:
vam.01
vam.02
vam.11
vam.12
vam.13
vam.14
vam.15
vam.16
vam.17
vam.18
vam.19
vam.20
vame.03a
vame.04a
vame.05a
vame.06a
vame.07a
vame.08a
vame.09a
vame.10a
vamex.03a
vamex.04a
So, I have no idea what I'm doing wrong. Could anyone help me?
