Re: [Rpcemu] New 0.9.2 Mac binary release

I should add, the disk I imaged was the original RISC PC disk which was a Conner CFS420A (https://www.computerhope.com/hdd/hdd0020.htm) with 63 sectors and 16 heads as required….

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:

<Screenshot 2020-04-27 at 20.33.10.png>

RISC OS 24MB

Supervisor

*dir aufs::4.$

Disc drive not known (Error number &108AC)

*

My setup looks like this:

pmoore@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">

<dict>

<key>NSNavLastRootDirectory</key>

<string>~/Downloads/classicroms/RiscPC_A7000/RO_370/DiscImage</string>

<key>NSNavPanelExpandedSizeForOpenMode</key>

<key>RPCEmuDataDir</key>

<string>/Users/pmoore/riscpc</string>

<key>RPCHotKeysGrabbed</key>

<false/>

</dict>

</plist>

and here you see the hard drive file:

pmoore@Petes-iMac:~ $ ls -l /Users/pmoore/riscpc/

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,

Pete

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).

I have tried to file some comments on GitHub but cannot find where to post them.  Guidance most welcome as I cannot get the program to run with a filesystem.

There is a new release of 0.9.2a that fixes this issue.  My packaging script was not including the "poduleroms" folder, which contains the modules for HostFS and its Filer module.  It was also including the "riscos-progs" folder which isn't required in a binary build.

You can download this from the same place as before:
