Create /ISO images

Hello, Does anyone know if you can natively create ISOs on RISC OS? I have a copy of the Acorn tool from circa 1996, but it’s just too old and I have major problems getting it to work. I’ve been backing all my original floppies up using !ADFImager and !ADFFS before entropy damages the data. I’ve moved onto my CD-ROMs now – I found a full multi OS copy of TextEase at work – the only RISC OS software they ever seemed to use and I’d like to back it up via ISO. I know I could do this on PC, but I’m sure it would garble the RISC OS filenames and types. Currently using RISC OS 3.70 (ROM) or 3.71 (Softload) or 4.02 (softload) on a StrongARM RISC PC, but I also have RISC OS 5.23 on my Pi 2 with USB CD ROM drive. Thanks, Matt |

To avoid that problem, I use !SparkFS to save the files into a RISCOS archive file and then use a PC to write the archive file onto the CD. Alternatively, SD cards are so cheap these days and you can get an awful lot of circa 1996 software onto 1 SD card (and then make a couple of read-only copies of that just in case). |

The PC should be able to maake an image copy of your CDs no matter what format the original content is. An Image is just an Image. |

On the RiscPC, there’s the option of CDVDBurn, but there doesn’t appear to be any support for USB writers (yet?) which could be useful on modern machines. On a PC, you’ll probably find the drive comes with the cut down version of Nero. It isn’t bad, once you’ve found the various options to tweak settings. Gets the job done and unlike the rubbish Brasero (Ubuntu), it can be told to burn your discs at a specific slow speed if going too fast tends to make tea cup mats out of the discs. On a PC with Ubuntu, don’t use Brasero. Three attempts and it ignored my request to write at 4x, preferring instead to try to spin the disc up to the maximum speed and then write to an unstable disc attempting to receive data about three times faster than the computer was able to provide. Honestly, I’m glad the disc write is the only thing Brasero managed to trash. I’ve never heard my writer sound like that before. It normally steps itself back if the disc gets unstable, but hey, Linux programmers know best, right? |

The native solution is commercial (65GBP) from Steffen Huber |

Yeah, I mentioned CDVDBurn. :-) Gotta love that exchange rate. £65 or €95. It’s not been like that for quite a while (hint, try ~£85 then blame Brexit). |

Of course the best idea is to buy CDVDBurn ( :-) ) – which in its latest incarnation (not released yet) also supports ARMv8 and USB – but there is a port of mkisofs around which once was bundled with the very first version of CDBurn when that didn’t have its own ISO creation code. 26bit only, command line only, from 1997, you get the picture. I might be able to dig it out… I also once developed a Java-based tool called “Isofier” which runs on Windows and Linux but understands HostFS and can interpret MimeMap files so can add CDFS extensions to keep the filetypes intact. Again, not released (yet?). The no-cost-solution is to zip the stuff up and use a PC to create the image. The zips will keep the filetypes intact. |

Nice! |

I’ve been adding ADF imaging to ADFFS over Christmas if you would like to try it. CD-ROM ISO creation is something I plan to add to ADFFS, along with mounting ISO and BIN/CUE support and CD Audio playback. I did a lot of work adding BIN/CUE and CD Audio support to CDfaker prior to the London Show so I could demo Heroes of Might and Magic. You can create an ISO in RISCOS with a few lines of code, you don’t need additional software. Use CD_ReadData to read data and then write it to a file. eg.

Does the ‘not released yet’ version of CDVDBurn write CDs/DVDs using an available USB writer? Alternatively with which models in current equipment like the ARMX6, etc? |

One of the reasons that it is as yet unreleased is that I need to test rather a lot of drives for compatibility. CDs usually work, as well as DVD-RAM, DVD+RW, BD-R and BD-RE. Not much luck with DVD-R until now. DVD-RW and DVD+R sometimes work. This needs to get solved before release. I aim for at least one current USB and one current S-ATA drive to be fully supported. USB models currently under test include the Asus BD-RW BW-16D1H-U Pro, the LG BE16NU50 and the Pioneer BDR-XD05TB. All current models. There are also older Samsung and LG drives available for compatibility tests. As well as the S-ATA drives combined with an S-ATA-USB adapter. |

I think the idea of the original request was to pack a bunch of files into an ISO image, not to create an ISO image from an existing CD/DVD/BD. |
