Resurrecting Nuance

[cubanral]

I wish I could have gotten further with it. The changes toxie has done make the code a lot more understandable. Still, no matter how many times I refactor things, I end up with the same crashes.

I don't have a very good understanding of the video interrupts. I tried to form some sort of relationship between the audio/video interrupts but the video just kept chugging along as if I wasn't even making changes. The audio seemed a lot more straightforward. Should the CPU effectively stall until the audio buffers are cleared?...who knows! It is such a high level emulation that things aren't really happening anywhere near how they originally did, including the ordering of some operations given the crashes. While it is nice to not have to think about timing, clearly there is something needed to give it some semblance of the original timing in at least in a couple circumstances. This emulator is especially frustrating since it is seemingly so close to making these games fully playable.

I just saw 3 Googlebots on this thread at the same time so something happened hopefully they will re-index this higher on emulation type stuff so we can get someone over from the Emulation scene to get us a NUON emulator! I know this can be done and will be done and I just hope it happens here! NUON Forever!

I want to go find the main Emulation reddit and put down a reverse psychology challenge - for instance like - there is no way you guys can emulate NUON! I have no idea what it takes to write an emulator except that I am sure it is not easy at all but I do know that the there are people in the Emulator community could do it if properly motivated....

I really do not know how far we are going to get with NUANCE though as it is Windows based.

I downloaded toxie's code for the emulator. I cleaned up a bunch of Visual Studio warnings. Not sure how to feed back the changes to toxie or whoever else is working on it. So, if you would like the cleaned up code, tell me how/where you want it uploaded.
This doesn't fix any bugs or features, just gets a cleaner build.

 

[The Helper]

That is very cool. What tools do you use to compile? Is it the latest Visual Studio?

I do not know where the latest version of the Emulator should go I know there is a source forge

Nuance

Download Nuance for free. An uneducated try to resurrect and modernize the Nuance NUON emulator. Unfortunately the author of the original project (Mike Perry) passed away a long time ago, but it seems like nobody picked up this piece of history and so there is no NUON emulator to be found...

sourceforge.net

Hey toxie are you there? Where can people upload the changes they made like dvhsfan did to the emulator fixing warning messages? What it is the central repository that we are going to use? I have noticed a great deal of activity in the web stat logs on this thread from my NUON update I made so I imagine there might be other people looking at it. We should have the sharing thing all set up before hand if possible. I do not know what is best for a project like this. Help?

Do you know anyone in the emulator community that can help?

I can definitely rebase my repo on toxie's changes from March. I ended up making a bit of a mess merging his changes. What I've done so far is mainly remove anything related to the non-functional cycle based emulation. With the hundreds of changes I've probably tried by now, I haven't fixed either of the crashes in Tempest 3000. Which version of Visual Studio did you use?

Nope, not a scene I'm involved in.

That is awesome! I love it. Please guys get together in some collaborative thing and share with us so we can all do it. You guys do not want to waste work. We need to work this out so we are working towards common goals.

 

[dvhsfan]

Which version of Visual Studio did you use?

Visual Studio 2019. Almost all of the warnings are gone. Only a few left. These were in the Nuance debugging code.
Looking forward to merging and producing a better emulator.
Would need to have instructions on performing the merge and uploading.

If anyone could add the _LoadGame bios calls that would be amazing! Would help me with testing code so much.

Being a NOOB to Nuon, is _LoadGame in some document ?
I MIGHT be able to add this call.
EdgeConnector, what are you testing and what are the results ?

Great, I'll use that too. I replied to your private message with further details.

It’s documented in SDK docs. It’s a bios call that will load the specified title from dvd by file name. Only works for signed files which should not be a problem now. It is also documented in the Nuance documentation as not implemented. This makes sense because no one could sign the binaries.

as per discord:
I got a port going for winXP... seems a bit slower tho but it's still runs great enough for homebrew dev

https://archive.org/details/nuance-resurrection-win-xp-compatible-files

 

[cubanral]

It looks like these files were removed. Would certainly still like to take a look at it though.

 

[mgarcia]

it was removed because it found two viruses in the codebase (the exe's NuanceResurrection-master/external/fmod-3.75/samples/multiple/multiple.exe and fmod-3.75/tools/asioconfig.exe )

here's the report link I got:

VirusTotal

I doubt it's an fmod issue, I noticed nudism.exe in both the old NuanceExperimental and resurrection but didn't think much of it (i'm not familiar with the code base)... doing a grep in the old archive, nudism isn't mentioned, so that's probably where it came from... not 100% sure tho, I'm going to scan my VM before uploading anything from it tho.

Nudism is a disassembler. I'm unsure why it started being included in the codebase. It should probably be removed from the repo as it isn't used. I removed some non-referenced source files and old builds from the repo already. Thoughts?

 

[Stephen]

It might be cool to see disassembled code, but I'm sure it would be impossible to understand so probably of limited use.

 

[The Helper]

It might be there to watch code values, or was going to like a debug view where you can see memory and values like in other emulators.
