You can download the build here: PCem-build-334-pcap-slirp.7z
This includes more different core binaries, and mostly fixes the NE2000 to no longer panic and fault out when something dumb tries to probe it, by writing the wrong values in the wrong places.
For the curious build 334 is right here. We didn’t make the feature cut for version 10, so hopefully it’ll make 11. I’ll provide an unofficial build once v10 is announced, along with hopefully better networking back end modules, expanding things from pcap & SLiRP.
