[Rpcemu] New 0.9.2 Mac binary release

Hi guys!

I installed the new RPCEmu, and managed to dump an image of my RISC PC 600 hard drive using `dd` on linux.

I copied the raw hard disk image to the RPCEmuDataDir as hd4.hdf and have RISC OS 3.60 roms in place.

I followed the instructions on https://www.marutan.net/rpcemu/manual/#hdf but when i run the first command I get the following error:



*dir aufs::4.$

Disc drive not known (Error number &108AC)

My setup looks like this:

pmoore at Petes-iMac:~ $ cat ~/Library/Preferences/org.devrx.RPCEmu.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
	<string>{712, 459}</string>

and here you see the hard drive file:

pmoore at Petes-iMac:~ $ ls -l /Users/pmoore/riscpc/
total 841744

-rw-r--r--@ 1 pmoore  staff        243 21 Mar  2017 rpc.cfg

Does the raw device file produced by dd need to be altered in any way for it to work?

On https://www.marutan.net/rpcemu/manual/#hdf, I couldn’t see exactly what format the hdf files need to be, so naively just tried using the raw file produced by dd, but suspect that might be the issue?

Thanks for anyone that can help, or redirect me to a better forum to ask the question.

Kind regards,

P.S. The dd command I used was `sudo dd of=hd4.hdf if=/dev/sdb` which generated the 420MB file which matches the size of the original hard drive. Running e.g. `strings hd4.hdf | grep Acorn` shows that the import seemed to work (there are lots of references to Acorn in the dump).
