Features:

  • SD/SDHC/SDXC support (tested up to 200GB; no exFAT support yet so SDXC cards must be reformatted using FAT32)
  • High quality push-push memory card slot
  • Fast ROM loading (~9MB/s)
  • Fast menu navigation
  • Directories are sorted automatically, no need for FAT sorting tools
  • High resolution menu (512×224) for adequate display of long file names
  • Real Time Clock
  • Supports ROM size up to 128MBit (96Mbit actually implemented as there are no larger known memory maps)
  • Automatic near-time SRAM saving to SD Card (while the game runs). Some limitations apply:
    • near-time saving is switched to periodic saving when a game is found to use the SRAM as work RAM.
    • Automatic saving is disabled when MSU1 is used. SRAM is saved on reset.
  • Enhancement chip support (see below for implementation status)
  • SuperCIC key (SNES CIC clone):
    • enables operation on unmodified consoles of all regions
    • supports software 50/60Hz switching on SuperCIC enhanced consoles only
  • Auto region patching: eliminates “This Game Pak is not designed…” messages regardless of 50/60Hz setting
  • Supports up to 16000 files per directory

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 rĂ©vision (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, 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 ?… Read more »

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?

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.… Read more »

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

Jessie12

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

sfc

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?

One33Seven

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… Read more »

Also I’m assuming the FPGA is XC3S400-4PQG208C as this is the only PQ208 Spartan 3 I can find.

I have been having the same issue with the MT45W8MW16, I have searched high and low for this part, even have asked suppliers for a suitable replacement and they don’t have any suggestions. “digikey”

I did find one website that says they have 25 in stock.
The site looks kinda iffy.
http://www.questcomp.com/QuestDetailsAll.aspx?pn=MT45W8MW16BGX-708WT&pnid=346509&stock=Yes

Is there going to be a redesign fitting a newer ram chip?
I would love to build my own unit but this is the only thing stopping me.

thanks
don

Godzil

The MT45W8MW16 is “deprecated” for digikey and is no longuer available, this is really sad as there is no real replacement with this pinout and there is no SDRAM or PSRAM chip of this size that could replace the MT45W8MW16…

How about sd2nes in the future? :-)

borti4938

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.

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!

The Retromancer

*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.

Denis

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

Dens

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.

Synnchan

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?

Dyne

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… Read more »

bandicoot

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

Antonio

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!

hk

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.

Nick

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

ME

Hi, Ikari. I was thinking about a way to do SA-1 AND Super FX, if the fpga really only has room left for one or the other.

Two Firmware releases, 1 with Sa-1 and another firmware with Super FX.

that way people could just use seperate sd cards, 1 for SFX and 1 for SA-1.
