Saving an ISO image of a CD

How can I save an ISO image of an existing data CD on my Iyonix?
If using CDVDBurn I can save data track but it loses the CD title.
I could extract all the data and create a new ISO Image but surely there is a simpler way?

I posted some example code showing how to go about creating an ISO if it’s any help.

Are you sure you want an ISO though and not a BIN/CUE? For that you’ll need to use another OS as you don’t get that level of access under RISCOS.

If you have a computer running linux with a CD/DVD drive, then you can simply “cat /dev/cdrom > file.iso”, which I have done in the past to back up old CD-ROMs.

No, it does not. The CD title is encoded inside the image data. Remount the image with CDFaker and you’ll see that the CD title is intact.

I think we need a port of cdrecord . It is already ported to Linux, MS-DOS/FreeDOS, Amiga OS, Atari TOS+MiNT, and many others, so I would expect it could be doable by someone more familiar with the stuff that comes from the unix world.

A port of cdrecord is tricky because of two things: first, it needs a specially implemented SCSI transport layer. The RISC OS SCSI stuff is unlike that of all other OSes (well, basically all OSes handle it completely different!). Second, it uses smake to build. Which is esoteric.

Smake and mirrors?

OK so how does the DOS version of cdrecord work if it requires an external SCSI transport layer?

DOS uses the same ASPI as old Windows (16bit ASPI). Nowadays, Windows has SPTI instead. IIRC cdrecord supports both. Explicitly. Just look at the sources. libscg is the SCSI part. There are seperate implementations for BSD, AtariST, AmigaOS, HP Apollo Unix, NeXTStep, VMS, UNixware, QNX, OS/2…

And what is smake not finding it on a quick search.

A “make” variant of the cdrecord developer. See https://sourceforge.net/projects/s-make/

Thanks for the correction. My memory isn’t what it was.
