If only it were deauthorized
^2. points to the count amount, so to speak, I don't know what what language this was originally written in, so it's probably very hard to hack it.
ResCompare (has been used before to crack these Opcode apps) might be the solution,
but I can't read HEX.

Reading the Galaxy Installation manual gives a bit of insight into how the protection works,
it even mentions "Do not try to edit the hidden file 'Galaxy auth -1 with ResEdit' or something like that!!

I have a feeling that using NybbleMaster and the modified DiskCopy 5.5 (hacked to allow Master Disk copying and writing) with a completely untouched, original Vision floppy, it's possible to duplicate it, with the authorization system (but the ability to clone it before)

challenge/authorize usually requires taking a nmber/letter sequence it gives and running some type of processing to get the authorization string; it appears it would require a keygen

mhm,
I believe this part of the "code" is the "Cryptographer" (screenshot)

I've been looking around the marketplaces for some floppies and they seem very scarce.. Let alone an untouched one?
Heck, I'm even thinking of emailing Oppenheim to see if he has any old archives!

The only other Master disk I have is a Cubasis for Mac (a friend gave it to me)
but it's in the same state; the computers it has been installed on haven't been deauthorized...
But I also managed to perfectly duplicate it with the instructions I sent you in PM (actually NybbleMaster can save the read image as a DiskCopy 4.x .image so no need for ShrinkWrap -I used it because DiskCopy 5.5 Modified couldn't read all .image filetypes)

So if you have a Master Disk that has authorizations on it, you can maybe try duplicating it, set aside the original and then try to install and authorize with a "properly" copied floppy?

Hi,

I have a Vision 2.0.8 master disk.  I also have a Vision 3.5.6 key disk, which has one authorization left on it.

I thought the way these key disks work, is that they have an intentional flaw on the disk which produces a read error on some specific track(s).  This makes them hard to copy, because most disk copiers cannot duplicate errors.  Maybe I'm wrong.

I'd be happy to make DART and/or Disk Copy images of these two disks for research purposes.

That would be interesting.
I did find a way to completely clone a disk (using Nibbler and Norton Ghost-something)
it was a different method which copies a floppy disk but by bit (or sector by sector I don’t remember)

You would need to do it on an older computer using these programs (I can send them to you if you want!)

You can use multidisk to create an virtual partition, authorise it, then copy the virtual partition, and then deauthorise  the copied partition....

I'm not sure if you can make a copy of the authorisation disk and then restore an authorisation to it with the above technique, but you can certainly copy the authorised multidisk partition file and post it here...

Vision is a music sequencing program, and Opcode's successor to the aptly named Sequencer, itself the successor to the even earlier MIDIMAC Sequencer. When audio editing capabilities were eventually added, Vision was initially renamed to "Audio Vision", eventually being renamed once again to the more familiar Studio Vision.
Unlike most sequencers that came after, MIDI management is handled from with the Vision application via MIDI Setup.

Hey hey, long time. I landed a huge collection of Opcode Vision floppies and manuals. Some of them sadly have no authorizations left. But some do; mainly 1.4 and 2.0.3 (or 2.0..

I just started experimenting with this process again, tonight. I actually managed to do this exactly; I installed the 2.0.3 version onto my Mac, used an old patcher I have and it restored the authorization back onto the Master disk and the program runs fine (like it's still authorized).
I haven't found a way to do it for the 1.4 version, but I might if I keep trucking!

Sidenote, I've made various attempts at copying/duplicating an original Master Floppy (with auths) and it is a more complex process like we've discussed before...

i gave up on this because of some other people who kept telling me lies about how easy this would be to accomplish yet they never dedicated any time or effort into even trying. i have vision working on my performa 5200CD authorized via floppy
