Firmware v1.10.3 is back up

Firmware v1.10.3 is back up

Firmware v1.10.3 is up again! The cause of the error was a silly copy&paste bug in a single place which could be fixed and retested easily. Only SuperFX was affected.

Thank you 🙂

Great !

Sa-1 games not working for me, sd2snes Mk2.

Super Mario RPG Work on 1.9, after update don’t Work anymore, Oshaberi Parodius on 1.10, after update same thing and Kirby Games don’t boot in all firmwares.

Let me get this straight. There are 3 different versions of v1.10.3? I don’t think you understand how software versioning works or the purpose of it.

I’m sorry, no offence was intended. It’s just very unusual and I find it very confusing, especially when checking out the source code and trying to figure out the code that matches the version. I’ve also noticed that the version number is usually bumped before the repository contains the changes for that version which only adds to the confusion. Just a small gripe, but overall I must say thank you for your hard work, much appreciated.

@Anon you don’t deserve ikari’s respect for an asshole comment. The guy is literally giving you great things and this is how you talk to him? I’d like to see you attempt the same thing he does and see how far you get. Get lost jerk. Learn some respect

What a shame this community is so hostile and that ikari would allow a comment through moderation like that of Hulkaroni&cheese. As I already mentioned, I found it confusing to identify the version of the source code I was working on. I regret my original comment, I now realise that could have worded it better and I have already apologised for it. I don’t know what else to say. I never asked for “ikari’s respect”, I don’t expect it either, nor do I expect an explanation for my original nitpick. As for “attempting the same thing”, I have no electronics… Read more »

DevLaTron? Is it you?


SA-1 games working fine except Kirby’s Dream Land 3 US version little video glitching loading map.

Thanks for the update 🙂

Hello, everything works fine with this version at the moment.
I have only a problem with the game Maerchen Adventure Cotton 100% (Japan).sfc but it was the same on old firmwares. The first time i load the game i get a black screen, but after resetting a couple of times (or more) it works.
My system is PAL with SuperCic.

I am having a problem with this and older firmwares on my, just arrived from krikzz store, Sd2snes Pro. My SNES is a PAL 1chip-02 with Supercic. I previously had the Sd2snes rev. H and in this regard it was working all right. Well the problem is that when I enable supercic pairing in configuration menu, the screen loses sync and the refresh rate goes crazy. I have an ossc and the screen shows the refresh rate and resolution quickly jumping to different random values. The only way to see something on screen again is to blindly revert supercic pairing… Read more »

Io ho un super famicom con flashcart sd2snes e mi da lo stesso problema


If you can, update the superCIC in your console with the last version of the lock file you find here :

It will fix your problem 🙂

SA-1 games looks to work again on my MKII now… But Super Mario Kart freezes on boot now 🙁

I was having the same issue until I replaced my DSP ROMs with fresh copies from the page in the FAQ. AFAIK it used to work on previous firmware versions so not sure why it suddenly stopped.

My mario kart freezes as well on boot on my sd2snes..

I just tested it. Latest firmware. Mario Kart runs fine. It’s on your guys end.

Hay the cart didnt come with the dsp files but it came with sa1 and the others. Weird..but i got it.

Thank you ikari !

Sir,i can can confirm there are problems with Super Mario Kart ! Different types of freezes during the Mushroom Cup first stage.

Sir … all good , Mario Kart working on first 4 stages that i played ! Tested on SNES Mini (my Sd2Snes it’s ref. f) and it’s all great.Also SA-1 & SDD-1 games working great ! Thank you for all !

the game “super famicom wars” freeze after you enter in the battle animation mode, this error doesnt happend in the previous versions!

Thank you so much ikari, and keep up the good work! 😀

Here’s a link to my custom menu.bin in case anyone’s interested:

Hi Ikari, I’ve picked up a new SD2SNES cartridge and loaded the firmware on it. It all seems to work but the games aren’t saving. I’ve read the FAQ and don’t think that anything applies to me. I’ve tried a soft reset and also made sure that I leave a few seconds for the save too. Either way, once I go back to the menu it and restart the game (SMW and Sim City for tests) there is no save game. I can’t see a save game file on the SD card either. I’ve added a saves directory to the… Read more »

SD2snes doesn’t have RTS, wich means it need you to go back to the menu before shutting down in order to save.
SD2snes pro has RTS function wich means it’ll save right away.
this still will not work for 100% of all games but should work for most games, games storing saves the common way.
i don’t think you really read everything though since it was in the paperwork when i last checked.

Jaap Daniels, this is absolutely incorrect. Save function is the same in sd2snes vanilla (mk2) or sd2snes pro (mk3). On both, only MSU-1 games need a soft reset to write a .srm. Besides that, it’s recommend you wait 2 to 3 seconds after saving, before shutting down SNES. More info and edge cases available on FAQ section.

John R, have you tried checking if your sdcard isn’t write protected? If you’re using a full size sd card (or a micro sd with an adapter) on sd2snes mk2 up to revision H, you need to set the switch on the card/adapter accordingly. Sd2snes saves automatically for most games, and you don’t even need to create a directory. If your sd2snes has a microsd slot, I can only recommend you try a different sdcard, with just a simple ROM, like SMW.

Great work! I didn’t buy an SD2SNES for its potential, because it was already the best at what it did back then, but as of late it has seen some massive improvements. Looking forward to seeing what else is coming (even though it basically already does everything for my purposes).

I’m currently having a strange issue with my SD2SNES. I’ve been playing the MSU-1 enhanced A Link to the Past, and the intro video sometimes spirals into corruption that gradually gets worse the longer it plays, and the sound starts to crackle until the screen goes black. The SNES still functions, if I hit start, it goes into the game as if nothing was wrong, and everything looks fine. The only other thing I’ve been having, is some 1-pixel tall lines of corruption on the edge of some of Kirby’s sprites in Kirby Super Star. Aside from those two things,… Read more »

You could try downloading the MSU file again. And make sure you get it from the original source, which would have been

In fact, 99% of all MSU1 hacks originate at Zeldix.

Looks like it was actually a problem with the SD card I was using. The access times were too long (was nearly 9ms), so I picked up an ultra high-speed SD from Sandisk, which has less than 1ms access time, and it worked out fine ever since.

Still have the weird sprite garbage in Kirby Super Star, but not sure what might be triggering that.

Hi Ikari:

I am also having this issue with Kirby Super Star. I have tried several different SD cards, firmware versions, and in-game settings (including turning on reset patch for clock phase) and nothing seems to fix it.

Any ideas as to what could be causing it and how to fix?

Thanks for all that you do!

Great project! I really appreciate the open-sourcedness of the firmware. I’ve been having some trouble and was wondering if you had any advice. I have a 2/1/1 SHVC-CPU-01 that has been giving me trouble with my Mk3 sd2snes (tried firmwares 1.10.2 and .3). No errors using the burn-in ROM for several hours, and no errors from the sd2snes debug firmware. The caps and regulator have been replaced and everything probes OK with a multimeter. Solder joints all look good under a microscope, including for the recap job, cart contacts are clean, etc. The symptom is that the video can cut… Read more »

does anyone know if somebody is still working on an implementation of the SPC7110 chip?
I found kmeisthax project, but that was not updated since last august.
I guess nobody is interested in it, because only far east of eden needs it… but it would be a shame, if one of the last big fan translation project can’t be played on the real hardware 🙁

Installing this update caused auto region patching to stop working for me. It acts juct as if it wasnt on/there.

My settings are:
Enable SuperCIC: Yes
Menu video mode: 60hz
Game video mode: Auto

I am running a 1-chip rev 2 PAL SNES.


My previous comment were ill informed. Since firmware 1.9.0 and forward auto region patching fails to work on Super Metroid (JU) and the MSU1 mod of Super Metroid on my PAL 1-CHIP 02 SNES This worked perfectly fine on 1.8.0 I have encountered the “This game pack is not designed for your SUPER FAMICOM” prior on 1.8.0 or earlier but was able to fix it using the button command L+R+Select+Y. Now this command now appears to do nothing.

Does not work on 1.10.3
Does not work on 1.9.0
Works on 1.8.0

I have the same problem. Since firmware 1.9.0 auto region patching fails.
My SNES version is exactly the same – PAL 1-CHIP 02.
So I can’t play Kirby’s Dream Land 3 with any firmware.

Hi Ikari I have question about cheat menu, is any chance to see it soon? I am excited for this 🙂
Thanks for reply

This version should probably be called 1.10.4 to clear any confusion.

srg320 developed a fpga implementation of the SPC7110 for snes_mister.
I wonder if could be used for sd2snes too?

Great, thanks for your reply! 🙂

Hi Ikari, I’m having a problem with R-Type 3 third lightning with Sd2snes pro 1.10.3 as the game starts in the first level stops working with graphical glitches, any clue ? thanks

yeah it did the trick thanks

I’ve found while playing through Mario RPG on the latest 1.10.3 my save would randomly delete itself. I would just get .srm online save files where I was to keep going but they would delete too. This occurred 3-4 times.

I just went thru mario rpg on this firmeware on super nt…i never had this prob..but im gonna play it somemore n. Save. An see if i can make it delte ..are u usin the pro or normal version..i luv too here more about this topic..

Well it’s the sd2snes pro. I would play and save. I’d shut down the system. Upon next powering up the save would possibly be gone.

When it would be gone I’d take the sd card and find the *.srm is still on the sd card though. I’d replace it with a .srm from a random save site and continue on.

A see one version of 1.10.3 has an issue corrupting ssd-1 saves. I’ll just revert to 1.10.2 for now and see how that goes.

I’m using the pro. I would play and save. I’d later power up the snes like normal and find the save deleted. I’d put my as card in the pc and find the .srm still exists so the file wasn’t deleted but the contents of the .srm must have become corrupted.

Hi, it’s not a hack or patched version. I was concerned that my other saves (I. E. Mario world, FF6, etc) were wiped but they are intact.

It might be some time until I have that data since it can be a couple days until the wipe occurs and I normally don’t play much until the weekend. I will copy over the intact .srm right away though.

Hi ikari, I noticed that I had saved my original file .srm which had lost it’s save data. I have yet to get a chance to play the game though. I only have google drive link though:

Here is the save i acquired online which I have been currently using which is good:

I will update if the ‘good’ save listed above fails. I’m hopeful the bad srm above shows some data you can use.

ikari, I do apologize! That save was another .srm from the internet. The condition that affected me was I only saved on slot 1 and upon next time powering up the system and game the slot was cleared.

I will continue to monitor the situation and update.

Just a short notice to confirm I also got this issue with 1.10.3.
Super Mario RPG save has reset after a break of a few month where I didn’t use the cartridge, wiping my 20 hours sessions.

After rebooting the console, it reset the save randomly.
In my case, I was using a version with french translation.

I have the old sd2nes rev G, not the pro.

il faux savoir que ikari est un faignant et un gros enculer , une petite merde d’allemand pourris du cul , a qui je mettrais bien mon point dans la gueule

désolé d’avoir été un peux dure avec vous monsieur IKARI mais il faut admettre que vous ne faites pas grand chose depuis la sortie du SD2snes Pro et sachez surtout aussi que c’est un outil illégale que vous avez fait envers nintendo ! , Donc je ne penses pas que nintendo appréciera votre travail et peux etre vous enverons t’il en procés ? , aprés j’ai été un peux dure sur les mots avec vous donc je m’excuses mais c’est la vérité , a moins que vous voulez que je vous signale a nintendo de votre activité sur une flashcard… Read more »

je vois que vous n’avez pas apprécié la vérité ? allez sans rancunes contre vous cher amis 🙂

ne vous inquiétez pas je ne dénonces jamais car je suis un gars correcte , pour moi le sujet est clos définitivement

Can we get save state support for the SD2SNES pro please?

can we get save state support for the sd2snes please?


Thank you so much for this !

Are you going to have to get a new domain name now that the SD gestapo have started demanding money?

hey is this the latest firmware? Because this has the sprite flickering issue (in Chrono Trigger with the Frog attack and Kirby Super Star) that was present before version 1.9

comment number 69. nice!

No progess on save states?

will the supersdpro ever get game genie support?

What the heck is the “supersdpro”?
It’s called “SD2SNES Pro”, if anything.
And even then, the SD2SNES Pro got renamed to “FXPAK Pro” a long time ago.
Plus, game genie has been work for heaven knows how long; your entire comment made zero sense and could have been answered by simply looking
up the most basic, essential info about the device online.

I think they mean cheat menu support.

Will be there any further official firmware releases? I see that there is huge amount of commits have been made since 1.10.3 release, but no official releases were published. Does that mean that the the users have to compile a new versions of firmware on their own from now on?

Um, hello? Is there anyone alive here? Ikari?
Is there a dedicated forum somewhere to discuss development and update news? Why is so quiet here? I want to stay informed.

Hi Ikari – I’m not sure if this is the best way to reach you for a question, but I’m going to give it a shot. So I spent the last 24-ish hours trying to get MSU-1 audio working correctly for Zelda LttP and Super Mario World (my first time experimenting with MSU-1 patching.) I had a 1-CHIP SNES, with an SD2SNES Pro hooked up to an OSSC via an RGB SCART cable, and then used the HDMI out from the OSSC to send the video/audio to my a/v receiver. The audio worked(!), but unfortunately I could hear a lot… Read more »
