It would probably be easier to use NetBSD 68k instead, if one wanted to. |

So, without wading through 5 pages, I gather this is a better OS than OS 3.9 due to the many fixes? I currently have OS 3.9 installed for my Towered A1200 with Mediator + Blizzard PPC + Voodoo 3 so wondered if it was worth upgrading it to OS 3.1.4 and can it be installed over an existing OS 3.9 install or has it got to be installed from scratch?
Would it also be better to wait and buy the physical ROM replacements/disks later rather than buy the ADF/ROM files now and then have to wait to buy the physical ROMS later? |

But would it be possible to reimplement (maybe with the help of this old compiler) this specific feature in question on a modern C compiler? Or is that far to complicated? (after all CGX is maybe not the only legacy software expecting it) |

As long as there is no documentation on how software such as CyberGraphX (and for that matter, Picasso II and MacroSystem Retina) interact with intuition.library, emulating the exact same behaviour will be very difficult. Not only would you have to know how the compiled code (using, for example, SAS/C) looks like, but also how a compatibility layer would fit in between the respective RTG solution and the recompiled intuition.library. And it's not only code behaviour which would have to be emulated, there's the data structures, too. Back in 1992 when out of the blue Commodore dropped Kickstart 3.0 and the A4000 on us unsuspecting developers, it was discovered that the "Picasso II" monitor "driver" no longer worked correctly with it (no surprise there). At the time the "Picasso II" supported screen dragging, and Kickstart 3.0 broke that. The "Picasso II" driver was subsequently updated to support screen dragging on Kickstart 3.0, too, but it required a major feat of reverse engineering. The data structures which allowed screen dragging to be emulated under Kickstart 2.04 changed significantly for Kickstart 3.0. The relevant information was attached to the non-public part of the intuition.library Screen data structure which in this form did not exist under Kickstart 2.04. How do you make sure that data structure compatibility reaches the same level as code compatibility? Tough one... Last edited by Olaf Barthel; 02 October 2018 at 15:33. |

@Olaf Barthel
Will the newly updated SetPatch be made available for free, like older versions have in the past? |

Thanks for the hard work Olaf, Thor & everyone involved!
Looking at the resident modules (A4000 version) one does stand out: dos.library dos 40.5 (24.7.1993) No bugs found in dos.library in the last 25 years 3.9 didn't update dos either IIRC. |

Commodore used to make SetPatch updates available when necessary (rarely), so there's definitely merit in doing so for the AmigaOS 3.1.4 update when the need arises. |

The last person to step up and do the job was, as far as I know, Colin Wenzel who is the AmigaOS4 dos.library Guru. We are indeed lucky to have him on the OS4 team. I do doubt, however, that Colin would be willing to look into the abyss that is the 68k dos.library again and wait for dos.library to blink first. |

Just placed my order for 3.1.4
I guess I will get a download link at some point via email? Edit, yep email popped up about 20 mins later. I'm off to play now... Last edited by kgc210; 02 October 2018 at 18:52. |

As long as it is not entirely clear, what the old compiler did, or what programs like CGX expect this is of course not really possible ... I was misled here (or misinterpreted) gullivers post: Quote:

@OS 3.1.4 developers
You might want to get someone to do some more promotion on this release. I see no announcement of any sort on Amigaworld.net or Amigans.net? |

The unpaid devs are doing all the PR work too just because they want to be involved and talk about their hard work.
Someone that's going to be paid for this should really handle more than just the money. |

Is there an installer script for these new Icons or do you have to manually install them?

I was promised nice GlowIcons. Where are they? On the Storage disk, glowicons folder. It has no icon itself, so use Workbench’s pulldown-menu to make it visible. Installation is a manual process for now. Insert Storage disk. Open a shell and enter: copy Storage3.1.4:glowicons/#? sys: all and reboot. |

If you will, what all these systems have in common in addition to making SVGA graphics hardware usable through graphics.library, intuition.library, etc. is that they leveraged the exec.library/SetFunction API to the max |

The Amiga 1200 Kickstart ROM does not scan the entire memory range which is reserved for the CD32 extension ROM and the FMV expansion, and it also lacks the driver software for the CD32-specific hardware, which includes the built-in CD-ROM drive. By using an Amiga 1200 Kickstart ROM in the CD32 you would likely be reducing the CD32 to an Amiga 1200 of sorts. |
