So i tried to get further so we could eventually boot homebrew games on DVD and earlier units like the Toshiba SD3200 which is a bit more common than the Samsungs units.

Anyway, while i made a bit more progress, i am stuck again.
The authenfication tools on Dragon Industries said the passphrase is "Past Is Prologue 6x7yc93".
That is not the case. I feel like employees must know the real meaning of Past is Prologue and are expected to replace it with what they were being told... but what ?
So my only resort is to brute force the GPG key. It is an El-Gamal 1024-bits key.
Unfortunately, it is not the weakest of keys.

The header itself however uses a MD5 hash, which should be easily hackable in theory but the Nuon also expects a certain header (which the bless tool does create it seems).
Thankfully, the NUON does not make use of BCA (unlike the PS1 and Saturn) but it's still not straightforward. The security is similar to the 3DO except said key is stronger.

Anyway, my computer ran out of memory and i couldn't any further.
I also don't plan on adding more DDR4 ram especially now... So if you happen to have a linux distro or WSL, then feel free to give it a try and brute force the key yourself :

https://github.com/gameblabla/nuon

The PGPCrack-Ng tells you how to run it. Use that along with my exported private key in the repo.
Maybe we'll get somewhere but i feel like this is just the beginning...
Anybody willing to give away or sell a NUON to me ? I'm in France and european models are impossible to find.

Just going to say this is good information. Always wanted to be able to burn the homebrews to DVD to play on the 2300 as that really is my favorite Nuon model. May have to tinker with this.

As for Nuons to spare, not at this time.

If you ever read this please post back I can arrange a NUON for you, it is not working but it is just the DVD drive mechanism should be an easy fix it is a N501. Also, I have contact info for Dragonshadow I can probably get that key.

How about this, I would be willing to send one of my N501s to France for you to try to encode homebrews. If you get it to work, I get to play Nuon homebrew games on my favorite 2300 and I no longer will need that extra N501 and you can keep it.

If you don't, you get to pay shipping back to America. :D

Interesting - not sure how I missed this thread. It showed up when I did a search of the passphrase :) I only have 16GB RAM in my machine. I wonder, if the program doesn't work on my machine, just how much RAM would be required? Pretty cheap and easy to spin up an Amazon EC2 instance for a temporary job like this.

    Hmm, how do I change my signature?
  • tom_mai78101 tom_mai78101:
    Signatures can be edit in your account profile. As for the old stuffs, I'm thinking it's because Blizzard is now under Microsoft, and because of Microsoft Xbox going the way it is, it's dreadful.

    Crazy how much 3d printing has come in the last few years. Sad that it's not as easily modifiable though
  • Varine Varine:
    I bought an Ender 3 during the pandemic and tinkered with it all the time. Just bought a Sovol, not as easy. I'm trying to make it use a different nozzle because I have a fuck ton of Volcanos, and they use what is basically a modified volcano that is just a smidge longer, and almost every part on this thing needs to be redone to make it work
  • Varine Varine:
    Luckily I have a 3d printer for that, I guess. But it's ridiculous. The regular volcanos are 21mm, these Sovol versions are about 23.5mm
  • Varine Varine:
    So, 2.5mm longer. But the thing that measures the bed is about 1.5mm above the nozzle, so if I swap it with a volcano then I'm 1mm behind it. So cool, new bracket to swap that, but THEN the fan shroud to direct air at the part is ALSO going to be .5mm to low, and so I need to redo that, but by doing that it is a little bit off where it should be blowing and it's throwing it at the heating block instead of the part, and fuck man
  • Varine Varine:
    I didn't realize they designed this entire thing to NOT be modded. I would have just got a fucking Bambu if I knew that, the whole point was I could fuck with this. And no one else makes shit for Sovol so I have to go through them, and they have... interesting pricing models. So I have a new extruder altogether that I'm taking apart and going to just design a whole new one to use my nozzles. Dumb design.
  • Varine Varine:
    Can't just buy a new heatblock, you need to get a whole hotend - so block, heater cartridge, thermistor, heatbreak, and nozzle. And they put this fucking paste in there so I can't take the thermistor or cartridge out with any ease, that's 30 dollars. Or you can get the whole extrudor with the direct driver AND that heatblock for like 50, but you still can't get any of it to come apart
  • Varine Varine:
    Partsbuilt has individual parts I found but they're expensive. I think I can get bits swapped around and make this work with generic shit though
