Assembly64 Preserve Commodore Files

Assembly64 is tool written by Fredrik Åberg in java that will provide you synchronization with  CSDB,,, C64 Gamebase and some others sites with Mostly Commodore 64 files cartridges, tapes and disk images, but there is also some Commodore 128 and  VIC20 content. Once you have downloaded selected content it will only downloads the delta content between local and available content on the server.

But it is not just tool that will download collection of almost all chosen Demos, Disc magazines,Games, Graphics, Intros, Misc,Tools and other Commodore related files to your hard drive/SD card, but it also allow to upload your stuff for preservation as well.

In example one can use Assembly64 to check their disks, this is done by verification of 8 checksums per entry, allowing single byte to be corrupt. of course same stands also for preservation and upload of files.

A Quick How to Start.

Now for some people Assembly64 site may be unavailable or even reported fake, this is because site is at the moment on and it does not have certificate, but be assured it is legit.

Another thing there is just bare minimum of manual how to start, but for windows user download unzip it, create Download64 folder where you want all the files and run, right click on “Installation” and “Add new location” and now point to wished folder.

For linux users do not follow instructions to download Java10 or Java11 from Oracle, java10 is abandoned, java11 is not supported. Due Oracle path with java future versions will be probably recompiled with java8 on all platforms.

Install java8 on your linux and download assembly64-j8-latest.jar, create Download64 folder and start java -jar assembly64-j8-latest.jar right click on “Installation” “Add new location” and point to  Download64 folder. And you may want to use light theme.

Now that you have installed from menu chose  what you want and there goes the download 🙂  In linux there is problem with browsing folders so use stock from your desktop that you use.

Now the part that I did not mention is that you have to register and that may or may not work, if it does not work find make a post on FB page and someone will help you.

When you select categories that you want to download it will download it quick in zip file, but zip will be unzipped! Author of this text did not select everything available and it already eat 29GB of disk space.

Another feature in Assembly64 is Chat, the line with Unknown is not really my handle, it is probably due registration bug.

From time to time make sure that you right click on Download64 folder and update all and for now do not expect daily updates.

Over all Assembly is good project and very usable software as it totally automate downloading of software and it is perfect for every Commodore user that want to have nice sorted and all available files on one place, ready to be uploaded to SD card and use in SD2IEC,Ultimate64,RPi1541 etc. And If this bring a big smile on your face consider donation for Assembly64 use and you will be not just Assembly64 Hero but you will get two options more Search and Sidify.

  1. Hello.
    I have a few questions regarding Assembly64. I hope you won’t mind answering. 🙂

    1. Regarding this statement… “In example one can use Assembly64 to check their disks, this is done by verification of 8 checksums per entry, allowing single byte to be corrupt. of course same stands also for preservation and upload of files.”

    How does this work exactly? Do you mean it can actually check the d64/g64 image or an original disk inserted into a drive connected to a PC using an adapter?

    The reason why I’m asking is because I have over 2500 original disks and I’m looking to make a set of images off of these originals instead of cracked versions that are currently found all over the web. I have the Super Card Pro and a modded 5.25″ drive to convert my original disks. If Assembly64 can somehow determine if my d64/g64 transferred images are corrupt or not, that would be awesome!

    2. You mention that the files can be uploaded to the Assembly64 website. Is it possible to alter this? I’d love to be able to upload to my NAS/File server over the Internet. It would be neat if the program allows you to select the url or site address where you wish to upload your images.

    Well, thats all for now.


  2. Hi,

    This is how “Elaine” in Assembly64 works.
    For each d64/d71/d81, 8 checksums/prg for all the prg’s are created where 7 of the 8 checksums
    have the same size, the last one is allowed to be longer or shorter due to compensate for more bytes appended to the end of each file .
    By doing this, single bytes of each prg are allowed to be “corrupted” and still end up as a “match” when
    compared in Elaine. So what the Assembly64 client does is to build up a jsonrequest where these checksums are created, and executes an endpoint on the serverside.
    This in turn validates the list of checksums against the database and returns a new json in the response pointing out the matches.

    So if you are
    1) A preserver which want’s to upload your d64’s yourself on csdb or other site you can you
    the bulkpreservetool to do this checking and you would instantly know if your 2500 d64’s contains any
    unpreserved files

    2) A non-presever which has a set of d64’s. Do exactly as in 1) but choose to upload the into the assembly64 cloud where a preserver will go through,examine and upload the fidnings on csdb
