FXPAK Pro (Base)


Light Pipes

SD Card Size


The "SD2SNES Pro" was re-branded to "FXPAK Pro" due to a trademark conflict. The FXPAK Pro still is the same great product, just with a new name!

This is the Base version of the FXPAK Pro for All Regions of the Super Famicom and SNES (it will fit into Japanese, European & North American systems). This cartridge comes assembled in a gray shell and a basic label.

Ever dream of having your whole library of SNES or SFC games in a single cartridge? The FXPAK Pro allows you to load your game back-ups (commonly known as ROMs) on a microSD card, put the microSD card into the FXPAK Pro, put the FXPAK Pro into a SNES or Super Famicom and have your list of games at your finger tips. Please read the FLASH CART DISCLAIMER below before purchasing.

    Cheats are a mess

    Posted by Derek on Jul 17th 2021

    There is no game genie support with this. You can add cheats, but it requires you to add them to the SD card, open up a program on your computer, change some of the text of the code, and toggle them on and off with hotkeys in game. For SNES games, that is just overly convoluted for 2021.
    There is no way to just boot up a game, and add an 8 digit game genie code. Really disappointing. I wish I knew before buying, because I might have gone with the everdrive X6 instead.

    Best flashcart ever made

    Posted by Santiago Sanchez on Jul 16th 2021

    I've had an sd2snes/fx pak since December of 2014.long before the pro, and long before any special chips were implemented, and it was still the best flashcart on the market for any system bar none. It's a labour of love that's come a long way, and still going.

    I must have tested every one of favorite game. Donkey Kong Country 1-3, super metroid, tactics ogre, final fantasy 4-6,so many. I've played translated games, prototypes, hacks, but the sd2snes really shines with features like the MSU-1 and it's ability to reduce hardware issues on later snes models like the white vertical bar on 1chip revisions and so on. Even the menu is customizable.

    Of course the best video game system in history needed the best flashcart, best 200 bucks I've ever spent.

    I wish I could tell you what the downsides are, but there are none, depending on your expectations. You don't even need a gameboy with an everdrive if you have the FX Pak Pro, you can just use the Super gameboy feature on the fxpak pro and play nearly every game on the library!

    Super Device

    Posted by AJ on Jul 14th 2021

    It’s a highly compatible SNES flashcart that runs everything I throw at it, special chipped games and all. Nothing beats the authentic feeling of playing the classics on the actual console itself. Furthermore romhacks tend to work flawlessly as well! Highly recommended for any fan of the SNES.

    Brilliant Flashcart and Product, One of the Best!

    Posted by Nikola Gutierrez on Jul 13th 2021

    Got this during when it was named the "SD2SNES Pro", and it has been one of the best investments I've made! Even for the high price of the best Everdrive version, it's great having the ability to play nearly every single game available for the console for all regions, and the benefit as well of being able to play many Super Nintendo games that make use of an Enhancement Chip is super appreciated for the effort on this Everdrive! It's just a fantastic deal all around, and as a streamer it is super convenient having a device like this to switch to whatever game I want, and being able to play any game via real hardware on my CRT just gives me the best feeling. Do yourself a favor and get one of these! :)

    Top-notch quality.

    Posted by Aaron Brown on Jun 28th 2021

    My FX-Pak came in a box sealed with SaG's oen witty gamer tape, the product inside was well-presented, the craftsmanship is top-notch, and it came with some very satisfying colletibles. An easy five stars!

    Fxpak Pro

    Posted by OG85 on Jun 26th 2021

    I owned the original SD2SNES before it was rebranded and found this to be the best way to play the SNES library on my Analogue SuperNT. I eventually sold my SuperNT and SD2Snes and upgraded to the FXpak Pro. Before I got into this I did some research, and found that this will play every game title in the library except for maybe 5? That's pretty amazing! Each game loads up super fast as well and save games work just fine. File management is super easy and setting up the Flashcart for the first time is pretty straight forward. If you are wanting a way to store your massive library of games on one cart then this is the way to do it. I know there are others available that are cheaper, but if you want the best then this is the cart to buy.

    FXPAK Pro

    Posted by SLF on Jun 26th 2021

    The price might seem a little steep at first glance but for the money you are getting a fantastic little product. If you are wanting to play SNES games on original hardware this is a wonderful way to do it. The menu is set up logically and navigating is a breeze. You can even modify the look of the menu if you so choose. The compatibility with helper chips like the Super FX puts this above other similar products. Being able to play games like Yoshi's Island and Mega Man X3 on an SD cart is something else! If you have any interest in playing homebrew, rom hacks, or game back-ups on real SNES hardware this is the cart to get!

    The best SNES flashcard on the market

    Posted by Frederick R on Jun 26th 2021

    First, I've been a user of the SD2SNES for years without issues. I'm passing my SD2SNES to a friend and upgrading myself to the Pro. The pro covers just about every game on the SNES. It works every time, feels as good as an official product.

    Great product! Better than I even imagined

    Posted by Braden Webb on Jun 23rd 2021

    This is great. I’m a Super Metroid speedrunner, and I got this just for practice on that game, but I found myself playing a bunch of other SNES games right away.
