The latest and greatest RGB bypass for the Sega Megadrive/Genesis console created by Lord Voultar himself and sold by us with his permission. This is the second revision of the PCB with all the latest fixes and improvements. At last, a 100% complete solution to the Sega Megadrive/Genesis jail-bar problem! This amazing little upgrade board squeezes the very best video quality out of your Sega Megadrive/Genesis console. Jailbars are eliminated (very minor traces may remain on some consoles when subjected to scrutiny) and sharpness is improved, going beyond what can be achieved using clean sync RGB cables or by lifting pins on the VDP. This upgrade delivers the absolute pinnacle of picture quality on original hardware, a must-buy for Sega Megadrive/Genesis fans!

Unlike our old model amp, this new mod will work with standard Megadrive RGB SCART cables too. Please note however that you MUST use a composite sync (clean sync, pure sync) cable and NOT a composite video for sync cable with this mod. Also note that composite video is disabled when using this modification and yes, for the one person at the back asking, that does mean the waterfalls in Sonic and other fake transparencies may not look like they did on your old CRT.

    This little board is awesome, really cannot fault the THS7314 for its ability to amplify analogue video. The thing I have noticed, however, is that it doesn’t play that nicely with the 32X. The 32X does work, but the graphics that the 32X overlays on top of what is rendered by the Mega Drive are shifted over to the left by one pixel. I cannot for the life of me work this out. I initially thought it was a sync problem, so I wired up the stock sync again and disconnected the sync output from the board, but still the same problem. Tried swapping parts out of my RGB cable and onto the board, same issue. Completely clueless.

      Interesting observation, I’ll look into that further.

      • Nick Andrews says:

        Did you get a chance to look into this?

        • BuckoA51 says:

          So far no, no other reports, but we’ve only sold a handful of bypass amps. Could you take a screenshot?

          • Ant says:

            could remove the 75ohm resister on the sync on the board see if that helps

            • Nick Andrews says:

              I already have mate, I’m running the stock sync from the Mega Drive without running it through the board. Though, to my understanding, all the board does is attach a pull-up resistor to the sync line and then through a cap and resistor that would normally be in the SCART head.

              • Iggy_Poop says:

                I would assume this is due to the filter the THS 7314 applies to the image. Try using the THS 7316 instead since it’s filterless. I use the THS 7316 on my SNES mini RGB bypass and when I apply the low pass filter through the OSSC you can see the image move to the right by a few pixels.

    Great picture after installing, Highly recommended.

  3. Burb says:

    Will these become available again at some point? Really sick of the jailbars in my otherwise perfect rgb picture.

  4. Jarska says:

    Any info on this? I’d be really interested but out of stock

  5. Matthew Miller says:

    Are these still in production? I can seem to find one for awhile now

  6. Luis Rivera says:

    Can’t wait til you guys release the new version. Once you’re in stock please feel free to take my money

  7. Chris says:

    Excited to purchase = )

  8. infidelity says:

    When will these be available for purchase again? I need one for my VA2 Genesis, thanks!

  9. infidelity says:

    Any word from Voultar? I’m very desperate in acquiring the rgb bypass for my model 1 genesis. :'(

  10. infidelity says:

    Please, when will these become available? :'(

  11. infidelity says:

    Please, when will these become available?? :'(

  12. John H. says:

    Do you have a version of this that comes with a THS7374 instead of the 7314? The 7374 is far superior to the 7314. Does this unit also have the option to disable the low pass filtering like most of the newer kits have? Lastly, will this also work on a Sega Master System? Thanks 🙂

  13. steve says:

    Will it work for mega drive model 2?

  14. cheesemaun says:

    Hey Guys,

    Looks like the new version of this board is out on – any plans to start stocking it and possibly the new DUORGB-X? (i’m in canada and they don’t ship lol)

  15. zack__1987 says:

    Are the new Voultar version of this board going to be available? I needed it getting shipped to Spain please!

  16. Hayden Gittins says:


    I see the comment earlier on in this thread about a potential problem with this and the 32X. Was there any further news on this?

    I’m looking at potentially getting a full MD, 32X and MegaCD region mod and potentially getting this put in as well. But if there’s problems with the 32X I’ll likely not go for it as I play most MD games through the 32x.

  17. Peter says:

    Any idea when these are going to be available again, have a couple of consoles in desperate need of a bypass.
