    Hello,
    i’m tempted to make one or two board based on your github data.
    A friend of mine work in pcb manufacturing and I can obtain some boards by him.
    But I don’t know if the last pcb révision (Rev.E) is stable enough or if I must take the “Rev. C” ?

    Please, have you some advice to make a working unit (i’m not hardware engineer but I shall understand a little) ?

    So anyway I thank you for sharing your work and for make things possible for SNES lovers !
    Good job !

    Kind regards, From France,
    Nicolas.

      Hi,
      please use Rev.E, there have been some pinout changes and the current firmware won’t work with Rev.C.
      To make a working unit you will need to:
      – make the PCB
      – solder all the components (except the PIC12F629). If you do it by hand, start with the BGA memory (and maybe the RAs) in a reflow oven, then do the rest. I recommend that you stuff the SD card slot last to minimize the chance of flux or cleaning agents getting inside, harming the push-push mechanism.
      – put a ferrite bead (SMD 0603) on JP341 (see http://www.flickr.com/photos/sd2snes/6251262232/sizes/l/in/photostream/ in the lower left)
      – solder JP401
      – program the PIC with the SuperCIC key firmware and solder it in (U331)

      That’s pretty much it hardware wise. To build the firmware and associated programs see src/README.
      Note that the active git branch is currently ‘develop’. The ‘master’ branch will be used for actual releases.

        Hi !

        Thank for your reply and for the advice !

        My boards are just arrived today so I’m entering in assembly phase now.
        I would ask you if you have some stocks of componments and if you sell “kits of parts” (componments only) ?
        I was thinking about you may have bought your parts in bulk and have few to sell…

        If not, I will be very pleased to know where you buyed yours and If you know a good supplier which had correct prices in Europe, especially for the FPGA chip (I’am from France) ?

        Anyway, I wish to thank you greatly for your support and dedication !
        Keep it good man, you make many people happy (count me in ! ^^).

        Beside that I’ve got my boards for a really low price (5 euros/board), so if I can give you one or two bare pcb for your tests or whatever, I will be more than happy to thank you with this very little !
        You’ve got my mail, feel free to ask.
        … feel free to delete this part of the message too. ^^

        I thank you again !
        Kind regards,
        Nicolas.

      Hi,

      I’m thinking of making a few boards myself but I have no experience ordering PCBs, I tried to get familiar with KiCAD but there are some odd things, the KiCAD site is down so I had to do with a mirror that I’m not sure is up to date, which may be why the silkscreen is overlapping all over the place and I have DRC errors I’m not sure are errors….

      Nicolas which rev did you use E,E2 ?
      If you still have a few bare pcbs, is there anyway I could buy one or more from you ?
      (I’m in France as well.)

      If anybody else is ordering some for themselves, please poke me, depending on where you order I might be willing to pay 50% more + shipping, that way you get 50% off on your own boards for the trouble.

      I found all the parts needed, the only thing stopping me is the pcb.

  2.  

    I might also be interested in a kit. I can likely get the PCB made, but the other parts would certainly be handy rather than tracking down each. As Nicolas cited, you probably have tracked down some reasonably good places to buy these things by this point! Just curious if this is an option you are considering or might be willing to arrange for a few of us?

  3.  

    Are you having any problems with the PRAM running at high speeds (meaning, the 104Mhz it’s rated for)? I was thinking of replacing it with a SDRAM module, but I’m not sure if a two-layer board like you have now will cut it, I fear of running into all sorts of signal degradation problems.

    Most boards I’ve seen go with four layers, I assume you didn’t because of cost?

    Also, these boards also seem to dispense with the termination resistors for the SDRAM, which I assume is because the isolation provided by the ground plane is deemed to be enough. I wonder if I could get away with keeping your two-layer design and adding those.

  4.  

    Would also love to see the sd2snes as a DIY kit.

  5.  

    Could you tell me if Sandisk SDSDX-064G-X46 works fine with it ?

  6.  

    some day if all of the special chips were supported, sd2snes could be a great wonder, although it almost is.
    ps: is there some other project planned? gb card for example

    Hi,

    I’ve checked out the 0.15 code and designs from github and I am using Eagle 6.4.0. I can open open all the designs in the cart folder except for the sd2snes20 designs. ERC goes crazy on the files with a huge list of errors.

    I’ve installed KiCad and I can open the RevE2 designs. However I am not fimiliar with KiCad and this is a huge burden. Is there something I am missing? Are the Eagle files incomplete?

    •  

      Indeed I ditched Eagle in favor of KiCAD even before starting work on the current sd2snes design. Thus the eagle files are quite outdated. Sorry. :)

  8.  

    I’m getting ready to order the parts from farnell but there are some weird parts on the BOM. Like these.

    FB RA103 ;
    FB RA104 ;
    FILTER FB341 ;
    FILTER FB342 ;

    FB are resistor arrays (obviously) but what value shoudl they be (guessing 100ohm)? And what is this filter? Just a ferrite coil?

    RA101 to RA114, which package should they be?

    The SDCard reader, the only one I can find is the DM1AA-SF-PEJ, is this the same one as I am having trouble checking the footprint with KiCad.

    CY62148EV30-ZSXI can’t find this specifically. Can only find CY62148EV30LL-45ZSXI, is this the same chip?

    BAT54C I can’t find this specifically but I can find BAT54C-GS08 and BAT54C-TP both of which have the same Vrrm Max bot have different Forward currents and Forward voltages. Which one of these is best suitable for the design?

    MT45W8MW16 I can’t seem to find this through the regular sources (Digikey and Farnell) any suggestions on where I can find this? And also, which type shoudl this chip be?

    And one final request, maybe switch the FPGA PQ208 package to something else as this package is extremely difficult to find.

    TIA

    How about sd2nes in the future? :-)

    •  

      It’s still “work in progress” :)… You may also work with the source code to help implementing some features. You can work on it and make a proposal for it to Ikari, if you finish it or if you still have some problems. :) You may also include functionalities you like to have on your own sd2snes. The complete source code is open sourced – use the GitHub project link on the right side.

  10.  

    Your “About” page should clearly and susinctly explain WTF “sd2snes” is. I have no idea by reading this site.

    Please explain what it is, at the top of your About page and FAQ!

    •  

      *amused* If you found your way here, you already KNOW what the SD2SNES is. And if not, a quick google search will clear that up right-quick.

  11.  

    ikari, is it possible to build sd2snes with XC3S500E?
    I have a couple of XC3S500EPQG208 but have no idea where to put them :-D

    •  

      Should certainly be possible but the Spartan 3E isn’t pin compatible with the Spartan 3 so you need to change the PCB layout and FPGA constraints file. Of course a different bitfile would be needed which makes it incompatible with firmware upgrades (official builds at least) ;)

  12.  

    Ok, I have build one :)
    But there is a problem, no picture on TV :(
    It seems all works as have to, I even found serial console output on TX3/RX3 :)
    Here is the output: http://pastebin.com/Ly1TXHUC
    Different firmware versions shows the same result, just black screen on TV :(
    Any help? :(

    SNES is working, I have test it with regular cart, works just fine.

  13.  

    Hey Ikari, I just got the PAL Version of sd2snes.

    Does that mean all of my games will run at 50fps?

    Or will the NTSC-U and NTSC-J roms run finely at 60fps?

  14.  

    Thank you for all your hard and dedicated work! I am having serious problems with my current SD2SNES unit.

    It has been working quite well and unfortunately, I only got the actual board so there is no shell or anything. It would boot fine on my SNES but now when I boot the unit in my console, there is no video or display of anything. Just a blank black screen. The LED’s and such indicate that the board is loading fine though… What could be the problem? It doesn’t seem broken and does not seem like anything has shorted. Just no screen anymore….

    Thank you.

  15.  

    thanks for all
    It seems there’s a problem with jurassic park when you enter in 3d mode with your last firmware release
    I try the first release of firmware and problem is gone
    hope it can help you

  16.  

    hello, i have one super famicom (year 1991) with no mod. complete untouched. I just bought SD2SNES and i am learning about. I tried to reset inside gameplay pressing L+R+SELECT+X, then it’s worked. can this damage the console or cartridge? that is so good feature. thank you, best regards!

  17.  

    Is there any way you could include an RSS feed so we can get a notification for your new posts? If you’d have to go out of your way I doubt it’s worth it to most people, but I for one would be very interested in getting updates, over email or RSS or something.

  18.  

    Hi Ikary, i would ask you if the improvment of the cartridge is still in progress.
