Official Home of ParaJVD ... Or how to turn an emulator into a full debugger!

Berzerk Video

Here is a video that shows the debugger in action :  Debugging Berzerk on ParaJVD

Nothing fancy, I'm just playing around with some of ParaJVD features, so that you can get a rough idea of the current state of the project, as well as its look and feel.

  • Looks awesome! Exactly what I need to start making Vectrex games. I've been trying to get DVE to run (for its debugger) without any luck. Any idea when this will be released?

    Hope it will be soon. :)

  • Thanks for your support, I hope you'll like it :)

    Sadly, there is still no release date planned yet (as I wouldn't want to set a deadline that I cannot honour).

    ParaJVD still requires some significant work to be brought to a state where it can be launched as a standalone application (on the TODO List is the Project Management module), and for some reasons, I always seem to run out of free time to work on it ;)

  • Very, Very Impressive, Franck !

    This is what we all are waiting for since a year of 10, I would say ! A self explaining environment.
    Btw, do You also have any intentions to support bank switching ? (using the PB6 line of the 6522 PIA, one could address 2 x 32K banks, if that line would be pulled up with a resistor to +5V.)

    You're a good programmer, I can say that for sure !

    Keep up the impressive work !

  • Thank you Kristof :)

    Yes, there will be some bank-switching feature eventually (maybe not in the first release, though), as I've started to work on this in ParaJVE (so ParaJVD will automatically inherit this feature).

    In fact, the memory banks handling code is already finished (ParaJVE can now load 64Kb binary) as well as the switching mechanism.

    Now I just have to write the generic code responsible for triggering the switch (I couldn't work out *when* to switch banks excatly, that's why I needed to finish the debugger first).

  • OK,

    Just let me know if If you have any questions regarding the PB6-line bank-switching.

  • looks really great, hope it will be released in the near future

  • Maybe not such a 'near' future, but the development is still on its way (the project management code has now reached a quite advanced status).

    I known I should communicate more about the advancements on this blog, but for some reasons I always find something better to do instead! ;)

  • Hi!

    I am interested into doing some Vectrex development.. Your tool looks amazing! How is it coming along?

  • Hi Bob,

    I haven't worked on it lastly, due to a major focus on the forthcoming emulator release...

    But as soon as ParaJVE v0.7.0 is out, I'm back to ParaJVD development. And it shouldn't take long before I'm able to build an alpha release for interested Vectrex developers.

  • Thanks! Please do!
    I don't know how to send my email privately, but I'd like to keep in touch. I just picked up a 3D Imager. Can't wait to try your IDE out.

  • Dear Parabellum,

    the ide looks great.

    Please continue developing.

    Looking forward for the release.

    Best Regards,

  • Hi, I admire your great job on ParaJVE, very nice.

    I'am a FPGA programmer, I currently released a VHDL port of the Vectrex console. I'am looking for information about Vecvoice and Vecvox interface. Data sent on joystick port was easy to match with SP0256-AL2 datasheet (ok for Veczerk or Y*A*S*I vecvoice). But data from Space Frenzy or Vvox-xmas doesn't match Speakjet datasheet (Vecvox). Unfortunatly I can't succeed in reaching Richard Hutchinson nor it's web site.

    It would be very kind if you can help me finding those information.

    Many thanks in advance.
