Resurrecting Nuance

mgarcia

You may change this now in User CP
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?
It's up to you, it's just a weird name! LOL
I've never uploaded win executables to archive before and didn't know it scans files like that.
I mounted the VM and ran ClamAV it didn't find any virus reported.
I also ran it in my NUON download/upload folder and zero virus found


Attached are the winXP build I use, it's about 10-20% slower in winXP compared to win7 VMware machine.

Download zip file of NuanceResurrection from github (https://github.com/andkrau/NuanceResurrection)
Copy and overwrite the attached files into the root folder.

2 out of all their anti virus vendors found a virus in my MSVC2010 executable:

The diff txt has the changes I made (mostly newer C++ hacks and boost for mutex), search for mgarcia.
I don't recommend changing your code base tho, it's fine as is.

Cool that you got it working under XP!

New build is attached to this post. Compatibility is expected to be the same. There should be less audio clipping (buffer underflow?). Let me know if any regressions are noticed. Thanks to dvhsfan for all of their commits.

Changes since Toxie's last commit:
  • Make sure enough time passed between audio interrupts
  • remove disassembler binary
  • Schedule audio interrupts in the same manner as the other interrupts
  • dvhsfan: further safety improvements
  • Correctly set DST
  • safe string and file handling
  • dvhsfan: correct bufSize detection in PrintInstructionCachePacket
  • ignore .user, .vs, debug/ and release/
  • Convert remaining printHandlers to make use of the buffer size
  • Remove old builds
  • Remove bUseCycleBasedTiming
  • Remove use of ProcessCycleBasedEvents
  • Make buffer size selection more straightforward
  • Remove unused files
  • dvhsfan: compiler warnings and general cleanup

NUON Lover!
Just build my first new PC in nearly a decade. Looking forward to trying the emulator and seeing how it performs on this rig (and also if it will work on a Windows 11 system). Pretty beefy system - i9-12900, 64GB DDR5-5600 RAM, GTX3070 vid card (waiting impatiently on the 4k series).

WOW - ok, runs the emu at a rock solid 60FPS and my breakout game works perfectly. Can't wait to try out some other stuff. This is high motiviation to revisit some of my old code.

Damn that's cool! I have all the SDK samples built but I don;t think my dumb ass made a list of ones I know that do not work.

Sorry I do not know the answer to your question regarding the emulator source.

Is https://github.com/andkrau/NuanceResurrection the most recent+active version of the codeline? I have a set of small fixes that get the MGL demos from the SDK working (They sort of work in Nuance 0.5.1, but the display is messed up, and don't work at all in 0.6.1). Well I've submitted a pull request. We'll see if anyone responds.
Yep, the commits from July are the most recent. I've done some stuff since then, but was really just experiments at sacrificing audio quality for the sake of stability. It was definitely not something worth committing.

I've merged your commit. I didn't notice any regressions when I tried it with commercial titles.

Turns out Nuance isn't actually rendering that image right. It's just a lot better than the blank screen it got before. It's not handling the texture mapping properly. It's just repeating some line (probably the first line) of each texture across the entire span, which for most textures in the room demo, actually looks pretty close to OK. However, I noticed it right away last week when testing my own code with some test textures purposely designed to show errors like this. I ordered some NOS high quality Sony CD-RW discs and verified the MGL code renders textures correctly on real HW (I'll post images of a correctly-rendered room demo for comparison soon when I have a Nuon hooked up to video capture again), so there's a more subtle bug in Nuance's handling of the MGL 3D library somewhere. Also, if you make the textures larger than 32x32, you either get a completely corrupted screen (at 64x64), or an error about an unhandled DMA operation from the Nuance BIOS handler code (128x128). Still need to verify those texture dimensions work on real hardware, but MGL claims support for up to 1024x1024 textures in its documentation.

    Hmm, how to summarize... Moved to the USA and got married. Became a professional software engineer and solution lead. Learning Godot for game dev. :)
  • jonas jonas:
    So you are pursuing game dev as a hobby? What industry is your dayjob in?
  • jonas jonas:
    FAANG?
  • Jesus4Lyf Jesus4Lyf:
    Not quite FAANG, less pay for a less hours/stress. Yeah, game dev as a hobby.
  • jonas jonas:
    makes sense. Do we have a hobby game dev subforum to showcase some work?

    "hey tom_mai please do not archive anymore news" ----> Got it. What should we do with the "News Archive" subforum?
  • The Helper The Helper:
    I think leave it for real old news that cannot be sorted the reason we had it in the first place was a server issue that we do not have anymore. I don't want to get rid of the archive just not put anything in it for now until we figure it out more
