    I just came across your SUPER FX ALL in One cart and wanted to know if it could be possible to have the overclocked versions of Star Fox 1 and 2 in this cart instead of the regular ones?


    1. wp_904 says:

      We will be able to make that happen with our new fx all in one boards soon. They are in line to be built, but we expect them to be ready to roll before Christmas. So not right now; I’ll be putting a newsletter together soon addressing this and a few other developments, and when we know they are ready to purchase we will insert that notification in the newsletter as well.

        Awesome. Thanks for your timely reply and I really look forward to it. Excellent site and products you have here.

    Ok so I had an idea for a great Genesis multi cart. Splatterhouse 2+3 together. Seeings how the price is crazy high for both I think it would sell really well. Maybe put the first one on too if possible.

    1. wp_904 says:

      That’s a great idea, I will surely get to work on that! Thanks Jeremiah!

  3. Randy Roberts says:

  4. James Gagne says:

    Any way you guys could make a ROTK 2,3 and 4 cart for snes?

  5. Cory Adams says:

    First of, I have purchased from you in the past, and have been very satisfied.
    On your old site you used to have a 3-in-1 of the ‘Super Star Wars’ trilogy for the SNES.
    Since I no longer see this game listed, I would like to see a 4-in-1 of the three
    ‘Super Star Wars’ games along with the similar is style,
    ‘Indiana ‘Jones’ Greatest Adventures’.

    I would also like to see it menu based, so you can choose which game you want to play at boot time.
    I would be interested in purchasing at least two copies of the cartridge I described.

    There are different SNES multicarts on the Internet that include Capcom games, but I haven’t really seen any for SNK (Takara) games.

    If possible, I’d love to see a Multicart featuring:
    Fatal Fury
    Art of Fighting
    Samurai Shodown
    King of the Monsters

  11. Jose says:

    I was wondering if you had a chance to test the latest VLDC9 from SMW Central on real hardware yet. It of course is sa-1. Could it be done??

  12. Shawn says:

    Will a TMNT 4 in 1 be possible?

    1. wp_904 says:

      Hi Shawn,
      As in nes TMNT+snes TMNT? If so, we do not possess the necessary skills to port games ourselves. 🙁

  13. Isaac Adams says:

    Is it possible to get Streets of Rage 1,2 &3 on a multicart? It would be nice to have a menu similar to the 6 Pak with SoR music in the background.

    1. wp_904 says:

      Yes, Streets of Rage multi cart will be available once the labels come in 🙂 I’ll try and gather more info on the whys of no menu for Genesis…

  14. Scott says:

    I’m also interested in VLDC9. Having 8 and 9 in the same cart would be a nice perk.

    1. wp_904 says:

      Hi Scott, we are currently working on 9 with help from a very close friend of ours, and it is proving to be a bit difficult, but we are confident we can make it play properly. We also agree on a combo cart, that would be cool! We will get there once we get over the first hurdle 🙂

  15. chris stubbs says:

    can you please make me a castlevania multicart hack like chorus of mysteries blood moon and ect would love one thanks

    1. wp_904 says:

      hi Chris, we will certainly try them and see if they’ll work on real hardware. No promises that we can get them to play, but we will try our best!

  16. Rico says:

  20. Rich says:

    Do you do nes carts too?

    1. Retro Circuits Admin says:

      No we don’t do NES carts- sorry!

      I think we’ve spoken about this already, but just in case other come across this comment…

  21. Karl says:

    Could with have a Jaleco Rushing beat collection, Rival Turf! (1992), Brawl Brothers (1993) and The Peace Keepers (1994). Not sure if theres any difference between the Japanese version to the US version and if ones set is better than the other??

    1. Karl says:

      Just read up on the series and it appears that:

      1st game is the game in all regions (bar name changes)
      2nd game the US version it the superior version
      3rd game the US release was butchered and the Japanese version is the better one.

      So it would defiantly be better to have the first 2 games of the US release and then the 3rd game maybe have a English translation patch applied to Japanese version (Rushing Beat Shura). If theres not such a patch available then maybe include Rushing Beat Shura (JPN 3rd game) as the bonus 4th game on the cart?, just a suggestion.

      Oh and please use the Japanese artwork for the games the US boxart is laughable 🙂

  22. Robert says:

    Hey gang, is it possible to put all the Phantasy Star games on 1 genesis cart?

  23. Norman says:

    Hello Retrocircuits

    I noticed the awesome wrestling super nintendo cart had more than 4 games. You guys sure say your prayers and take your vitamins!
    I was wondering what conditions allow for more than 4 games?
    Is it a memory limit?

  24. Kristoffer S says:


    Is it possible to get a cartridge with “Tengai Makyou Zero” (Far East of Eden Zero) with the new English 2.0 patch?

    1. Retro Circuits Admin says:

      Thanks Kristoffer!
