Firmware update at



Thanks for the Sd2snes

I am very satisfied with the cartridge although days after the pro version came out, I am still taking full advantage of the cartridge functions.Thanks the speed of the shipment, arrived quickly to Peru, only that my local mail was delayed in delivering me but from there everything is satisfied, next to the Turbo Everdrive of PC Engine, I am recommending to some friends, I hope in these days to make other orders, Thank you.
Now I am enjoying the MSU roms


I love the SD2SNES, it's so bad!

A cartridge allowing you to play 99.5% of the entire SNES library. Plus, it adds PCM audio, FMV, rom hacks, BS-X and, best of all, keeps your clock ticking. A must have for Nintendo fanatics, however there's a new pro version coming out with a better FPGA, potentially expanding the game support up to 100% and MAYBE adding Super GameBoy support. Regardless, buy this right now or wait a bit if you want the BESTEST of models.

Simply incredible, worth every penny. MSU-1 patches will blow your mind, particularly on a Super NT. The patch for ALTTP, FF3 and TMNT4 absolutely flabbergasted me...not to mention it runs most rom hacks and every translation I've tried. If you want an SD flash cart just spend the extra money and get this, you will not be disappointed!


Great product

I am very happy with my sd2snes! I highly recommend one if you are on the fence. I mostly purchased this to play english translations of Japanese games we never got in the US (FF5, Fire Emblem games, etc.). To my surprise, this cart plays *everything* I've tried perfectly. Even games that use SuperFX work great. I was worried the expansion chips would have slow down, but so far everything works great (FYI - Star Fox shows a bit of slowdown on youtube, but it is hardly noticeable to me). So far, I've been playing all my SNES games on this flashcart, highly recommended.

One thing I was mainly worried about was shipping to the US, but it really isn't too bad. I used the "17TRACK" Android app for realtime shipping updates. Also, I'm pretty sure it required a signature, which is good news for an expensive package. It did seem to take ~20 days total, so keep that in mind.

Great product

I'm really happy with this. It's nice to be able to play Japanese translations on my SuperNT and US SNES.

Does what it says on the tin

Super cartridge, very happy with this product! I use this on a Modified PAL SNES with a 60hz switch, unmodified Super Famicom 01-Chip and my Super NT, all work flawlessly. MSU-1 works great after reading instructions online. Plus Super FX is now supported and SA-1 are becoming supported, so 100% compatibility is almost there.

I wish there was a cheat function, but this might be added later on down the line and the option to get back to the menu from the file folder you were previously in after the shortcut buttons to get back to the menu would be a good feature thats similar to the Everdrives functionality.

Well worth the price and shipping is around 15 days from the Ukraine to the UK. So this is fairly quick.

Works as advertised (!), setup is fairly easy even tough instructions are a bit sparse, arrived within 16 days.


The best accessory for your SNES/SFC!

Such a superb product. I've had my SD2SNES for over a year now and it's given me nothing but joy. And with the recent addition of Super FX support it's even better! Don't be turned off by the extreme cost, it truly is worth the price. Don't settle for cheap Chinese clones. Go Krikzz or go home.

Super great product

I love the way this cartridge manages my game collection... I love that I can play all the games that my nostalgia brings to my mind... this is the definitive way to play SNES games!! AWESOME

Fantastic value!

No need for a room with a huge shelve for 700+ games, the SD2SNES got you covered on a single micoSD.
But you will have to complete the collection with original SuperFX and SA-1 games, since the SD2SNES doesn't support these yet (if ever).

Overall fantastic value,, a must own for everyone who likes the real SNES/SFC experience instead emulation without shedding thousands of dollars collecting cartridges.

SD2SNES is a amazing device, I'm now able to play games I never had a chance to play when I was a child.
It's a "must-have" if you still own a SNES. Remember that games that have FX chips can't be played. Hope someday in the future ikari_01 will implement it by a firmware update.
(P.S: The MSU-1 feature is outstanding!)

Best Flash cart ever!!

A massively awesome cart which plays a huge chunk of the SNES/SFC library as well as some amazing MSU1 games. Can't wait for more awesome updates!

What a wonderful feeling to play all of my favorites on original hardware again! SD2SNES works amazingly on my Super Famicom. Games load instantly. Easy to set up too. Definitely worth the price!

Perfect for more than developing

Runs on multiple platforms, I own a classic SNES American push eject style, many other clones, and it runs on all of them. Modifying is simpler than the others I've played with. By the time I'm done I'll have one for each of my libraries for consoles. There's no better way to preserve your retro collection than by using a method like this, of course there are others but it's just not the same if you're not whipping some alien ass on Contra III with the SNES console and controller. The earlier model is perfect for those whom are just into random playing and don't care for "tinkering" with the other capabilities of the card, in my opinion it is amazing technology and I highly reccomend as I own many of them this far and am more than pleased.

Color may vary

I got a translucent red cart, so you might not get a black cart; just wanted to let others know.

This uses a regular-sized SD-card label-side facing towards the front.

For the firmware, don't go to the Downloads tab on the top of this page, but go down beneath the description of this product.

It's a bit sensitive.

Another reviewer said his early-version SNES (with the locking mechanism) is incompatible with the all-region cartridge shell Krikzz uses. My Super Famicom locking mechanism seems to work fine.

I haven't used or analyzed it very much, so I'll probably edit this review and adjust the rating.

I bought a brand new SanDisk 32GB SD card (from Walmart) and loaded a curated ROM pack (SmokeMonster 3.4) and it worked, but it included an older SD2SNES firmware. I accidentally loaded Izzy's Quest for the Olympic Rings and noticed it conflicts with the special controller hooks. Hopefully there's a way to make it automaticallly disable hooks for specific games. Anyway, the SmokeMonster 3.5 set was released the next day, which includes the latest SD2SNES firmware/OS. The latest specifically has improvements to in-game hook compatibility. I formatted the SD card in Windows and extracted the latest set directly to it. Now, the screen goes blank when I load a ROM. Disabling hooks doesn't help. Re-extracting the latest SD2SNES firmware and over-writing the SD2SNES folder didn't help. I had to revert to the much older firmware that SmokeMonster had included in his 3.4 set and now it works again.

Awesome product, but not 100% perfect

First, I should mention that I own the NTSC SNES with the lock mechanism. The plastic cartridge would not fully insert into the connector because the locking mechanism kept the cart a little too high. This created issues with several games (random freezes). If you have this issue, you can either remove the locking mechanism (fairly easy if you have the SNES security bit), make your own shell out of a real SNES cart (e.g. Mario Paint) or simply plug the PCB directly in the SNES.

Krikzz manufactured this and it is perfect. The only issue I have is that for years we were promised more support for the enhancement chips, however I haven't seen any improvement in years now. This is for the person who designs the cart and wrote the software, but keep in mind that if you're buying this now you're not getting SuperFX support and buy this thinking you will never get it. If it comes later, it will be a bonus.
