Then back to the T3K deadlock issue..

One theory i have is the following: Could it be that due to the way the 'instantaneous' DMAs/Comms/etc work in Nuance, that T3K actually relies on these operations to take more cycles than 1?
So that the operations are executed too fast and thus the T3K code cannot react accordingly?
I wonder how one could fix/workaround this.
Add a queue that delays the signalling of certain operations?
Or delay the execution of certain commands by the spec'ed amount of cycles?

I would just slow everything down and work up. Add a bunch of delays and cut them and just brute force it. It is all about the timing.

Its not that straight forward though. One would have to buffer things that should be in flight whereas at the moment things are 'just done'.
But maybe its the only solution, who knows. (Jeffs source code could tell ;))

I just tweaked some more things in your commit, could you please doublecheck/review?
Looked through all the code, yes, great cleanups. Feel free to also delete all the unused variables you commented out, and the commented out code I left as notes to myself during intermediate changes that got squashed and then forgot to delete before sending the pull request. Oof. I even proof-read this.

Could you make a PR for this? Cause i don't know exactly which code/comments you mean. Thanks!

It is not dumped yet. when I look at the files, Tetris isn't there, even though it lists it to be there.

hopefully songbird will release it soon so we can finally play The Next Tetris without paying $800, Ebay has good deals for some stuff though, I remember one time when the Nuon was on there for $300 with everything with it, after all the controllers are hard to get.

It's actually dumped, didnt research about the next tetris. it's not actually called the next tetris, it's actually called toshiba sampler

Toshiba Sampler contains the only The Next Tetris official release.

While testing Nuance on my laptop, I noticed that the Tempest 3000 demo on the Toshiba sampler also crashes every time trying to start the game. Not sure it will help find the issue, but just another data point.

I by now also experimented with that one. So waiting on the respective MPE until a DMA is finished up, similar to the real HW, but with no positive change. Instead, obviously the emulation just got slower overall. :/

I don't think that would help. This is either some race condition somewhere, or something unhandled in general in the emulation.
Or some wrong opcode emulation.
I'm currently checking things all over the place in the hope to find more details.

But i desperately still need somebody skilled in Nuon development to reverse engineer T3Ks music (loading) code.
Or somebody with connections to Jeff Minter himself, cause he didn't answer my questions so far. Maybe he would be willing to share the source, or at least the respective snippets.
 
General chit-chat

  • No one is chatting at the moment.
  • Varine Varine:
    I want to build a filtration system for my 3d printer, and that shit is so much more complicated than I thought it would be
  • Varine Varine:
    Apparently ABS emits styrene particulates which can be like .2 micrometers, which idk if the VOC detectors I have can even catch that
  • Varine Varine:
    Anyway I need to get some of those sensors and two air pressure sensors installed before an after the filters, which I need to figure out how to calculate the necessary pressure for and I have yet to find anything that tells me how to actually do that, just the cfm ratings
  • Varine Varine:
    And then I have to set up an arduino board to read those sensors, which I also don't know very much about but I have a whole bunch of crash course things for that
  • Varine Varine:
    These sensors are also a lot more than I thought they would be. Like 5 to 10 each, idk why but I assumed they would be like 2 dollars
  • Varine Varine:
    Another issue I'm learning is that a lot of the air quality sensors don't work at very high ambient temperatures. I'm planning on heating this enclosure to like 60C or so, and that's the upper limit of their functionality
  • Varine Varine:
    Although I don't know if I need to actually actively heat it or just let the plate and hotend bring the ambient temp to whatever it will, but even then I need to figure out an exfiltration for hot air. I think I kind of know what to do but it's still fucking confusing
  • The Helper The Helper:
    Maybe you could find some of that information from AC tech - like how they detect freon and such
  • Varine Varine:
    That's mostly what I've been looking at
  • Varine Varine:
    I don't think I'm dealing with quite the same pressures though, at the very least its a significantly smaller system. For the time being I'm just going to put together a quick scrubby box though and hope it works good enough to not make my house toxic
  • Varine Varine:
    I mean I don't use this enough to pose any significant danger I don't think, but I would still rather not be throwing styrene all over the air

    I bitch about Xenforo sometimes but it really is full featured you just have to really know what you are doing to get the most out of it.
  • The Helper The Helper:
    It is just not easy to fix styles and customize but it definitely can be done
  • The Helper The Helper:
    I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
