    Wow, you can read the date on the newspaper now @ 0:52! This is even better in motion than the stills you posted before, incredible!

    Also look at the difference overall in that sequence... lovely diagonals, much more "natural" looking too

    Original encodings (with dynamic background switches) took around 1480 msec per frame. (30 frames per second).

    That doesn't seem right. 1480ms per frame is not 30 frames per second!

    It's more like 2/3rds of a frame per second, by my calculations anyway.

    any news about your fantastic tech demos - maybe a bin file for the „real thing“ and (let me dream) a PAL60 version? 🥳

    I will come back to this sometime; I think it has a lot of potential and was fun.

    But for the short/medium term I will probably not be working on it; I have studies which should be taking up my time for the foreseeable future.

    Hi there,
    I have doubts that my console is PAL, because it displays properly my demo written in NTSC manner (262 scanlines), the proportions of the screen are also ok, so I wish to ask whether most of the demoscene productions dedicated to PAL consoles will lose synchronization on NTSC machines just like in Stella emulator? For example demos SV2020 and 2600BC are displayed ok on my console but on emulator they lose synchronization in NTSC settings.

    It's your TV that decides if it can display the frame OK. Some TVs can display both NTSC and PAL signals, with autodetect. Many TVs can display "out-of-spec" frames. If you have a 262 scanline demo, you can't really know if it's running on a PAL or NTSC console until you check the colours on the TV. That's the main difference between the two - the frequency/location of the colour information in the signal output by the console. Other than that, the consoles are very close to identical. Very minor difference in clock frequency, but it's negligible.  Your question is really slightly worded incorrectly; it's not the console that determines if a demo will lose synch; it's the TV.  If the TV is incapable of displaying the # scanlines sent to it, you get a wonky picture, or no picture at all. Nothing to do with the console. Everything to do with the demo itself.  You'll get the same wonky picture (just with or without colour) using either an NTSC or PAL console on any given TV. So again, the only real way to determine by looking at things is if the colours are correct on the TV. If they are, then you probably have a console/TV match (both NTSC or both PAL).

  5. What I really love about the ebay ad is in the very first line of blurb...



    The rarity of this game and it's history does not lie.  Its simple logic


    It takes special skill to get "it's" and "its" wrong in consecutive sentences.

    I'm going to have to read the rest in instalments; I don't think I can stand such stimulation in one go.



    Puts it into prospective for you 


    Yes.  Yes, it really does. Wait, what?

    Thanks for clarifying. I love what's happening with this project, and I hope one day we can see some cart technology that works :)

    That already exists - it was demonstrated on the ZPH show, I'm pretty sure.  All the hardware and software is open sourced so there's always the opportunity to build one for yourself.

    So let me ask this, because I haven't done anything with a final file...


    Can a movie file be loaded to my regular Harmony cart and played from my Atari 2600? I would love to see it, just for the sake of playing around with it.

    No, not at this stage. I do not think Harmony currently supports MVC files/format.

    I know "Wizard of Speed and Time" (1988) has Jittlov's approval for sharing, as long as no one is making money from the film.


    That feature-length film can be seen here: https://archive.org/details/WizardSpeedTime

    TY I will have a look at it and maybe encode.

    1 hour ago, keithbk said:

    Is the final file a BIN file? Just curious...

    It's effectively a data file with the encoded movie, that is stored on the cart's SD card. This file is effectively a bin that the emulators can load/play, too. Stella and Gopher emulators currently support the moviecart playback. To view on actual hardware you would need an actual MovieCart hardware board at this stage.  I'm hopeful that eventually the PlusCart can have firmware to support, too. But... that's way in the future.





  8. This is so much fun to play with. And it keeps getting better and better. It's astounding how good some of the encodings are. I'm just playing around the edges learning how various tweaks affect the output. Even though I know how it's all encoded, I'm still astounded at the results. So clever. Can't wait to see it as a released product. Video is screen-grabbed from stella playing the MovieCart file. My system can only manage about 35fps.

    The MVC file playing on Stella looks much nicer.

    I dont think anything I said warranted your hostility, but I apologize for giving offense by asking a question. Good day!

    Disagreeing with someone isn't being hostile to them.

    Hey Dion!

    This is THE Steve Wright that wrote the Stella Programmer's Guide so many years ago. Thanks for formatting my programming guide into a book version. I had no idea that so many people are still interested in programming games for the 2600. There was absolutely no information on programming the chip set when I started at Atari so I decided to sit down and learn everything about the chip and how to program it before I wrote my first game which was Championship Soccer which later was rebranded as Pele's Championship Soccer. Loved my days at Atari! Long live Classic Gaming!!


    Doing another Atari interview next week for the Video Game Newsroom Time Machine. You can check them out at https://videogamenewsroomtimemachine.libsyn.com/


    Good to see you here, Steve.

    So, what do you think of the modern homebrew works like Aardvark, Galagon, and the MovieCart... to name a few?


  11. Some names, to me, defined AtariAge and what community meant. Nukey Shay was one of those. 

    I think we should all be required to post to the forum a "proof of life" photo holding the day's newspaper, at least once a week.

    Two years is way too long for us to have noticed this.

    I only mentioned what I did when I noticed it wouldn't fit into the slot of a 4switcher I was servicing at the time I received my cart. Filing down the corners of the cart with about a 45° taper about 2 inches from the bottom up took care of this. It still rubs a little when inserting the cart into my 7800.


    In looking at the dust pegs again and comparing them with other carts, they actually look they are fine on the length. I haven't tried it in a stock 7800 but it did seem to seat all the way down on a 2600jr. Although the corners were still a tad tight when inserting it.


    I believe my cartridge shell is one of the just prior versions where the plus cart symbol is a separate piece from the rest of the cart that is on the back and it has white colored dust door pegs if that helps?



    OK, TY.

    I will send you a replacement, please PM me your address.
