FXPAK Pro (Classic)


Light Pipes


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, red anodized screws and a Classic-style 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.

Basic Edition vs. Deluxe Edition

The Basic Edition comes with just the FXPAK Pro cartridge with a gray back label in the selected style or configuration covered by a 1-year Warranty. Whereas the Deluxe Edition includes the cartridge with gold back label, a case, printed manual, an FXPAK Pro sticker, Stone Age Gamer sticker, and is covered by a 2-year Warranty.

    • enables operation on unmodified consoles of all regions.

    FX Pak Pro

    Posted by Enric Ferrer on Jul 26th 2021

    High quality product. Very easy to configure. I have tried all the ROMs that I wanted and they all loaded quickly and without any problem. It works fine together with OSSC.
    The addition of the MSU-1 chip is brutal! Graphics and music like the SegaCD of the time.
    Without a doubt, highly recommended product. You have the complete SNES catalog in a single cartridge.
    The shipment by StoneAge Gamer has been perfect, the package has arrived in excellent condition.

    El añadido del chip MSU-1 es brutal! Graficos y musica como el SegaCD de la epoca.
    Sin duda, producto muy recomendado. Tienes el catalogo completo de SNES en un solo cartucho.
    El envio por parte de StoneAge Gamer ha sido perfecto, el paquete ha llegado en excelentes condiciones.

    Better than the real thing

    Great for hacks, translations, and for saving thousands on the original carts. Plays almost every game, highly recommend the FXPAKPRO.

    FXPAK PRO is perfect!

    Posted by Michael C. on Jul 5th 2021

    I spent a lot of time researching the pros and cons of jailbreaking my Super NT vs using the FXPAK Pro. Ultimately, having the ability of save states and a much nicer look to the game menu interface sold me. At checkout, I chose no SD card & the extra pack. The extra pack included a case for the cartridge (looks kinda like a hard plastic Blockbuster case), some stickers, and an instruction manual for FXPAK Pro. Well worth the extra money.

    Using a Mini SD card with the FXPAK Pro, I've loaded every US game, every European game, and a lot of translated games. Every single one has played flawlessly.

    I've literally had no issues whatsoever with this cartridge. So much so, that I just bought the N8 Pro minutes ago.

    The Perfect Cartridge for your SNES Needs

    Posted by Matthew Baker on Apr 10th 2021

    I purchased my FXPAK Pro well over a year ago after weighing my options for several months and I was blown away by the degree of quality I was met with. I needed a flash cart that would handle a vast majority of the special chip games that make up so many of my childhood memories of the SNES and it handled everything I threw at it with flying colors. It’s truly a marvel of engineering.

    Now as for a review of the physical attributes of the cart the variant of FXPAK Pro I purchased was a basic grey North American cartridge shell in the Classic flavor and I thought if I was going to go all out I might as well spring for the Deluxe version while I was at it. I was met with a sturdy jet black Bit Box themed to match my cartridge with a matching printed instruction manual, logo sticker, and Stone Age Gaming sticker placed in the inner pocket of the box. It was a bit larger than I expected and reminded me a lot of the large bubbled plastic VHS cases that were used for some of the premium movie releases back in the day. It was large enough to accommodate the cartridge and all of its supplementary content securely and that’s really all I could ask of it. The cartridge casing was machined very well. The plastic is sturdy and the the stickers look nice with a satin finish. I will say that the only minor flaw I noticed was that the hole machined for the microSD card did seem just a hair too large for the actual micro SD slot but if you’re paying attention to what you’re doing when you plug the card in you’ll never even notice that as an issue.

    In summery the FXPAK Pro has been and still is a wonderful addition to my setup and I couldn’t possibly recommend it more.

    Exactly w4hat I was looking for!

    Posted by JS on Apr 4th 2021

    There isn't much I can say about the FXPAK Pro that hasn't already been covered. I highly recommend My Life in Gaming's video on flash carts to get a good rundown on the uses of these. In my case, it's seeing great use in some hacks I've been wanting to play on original hardware on my CRT, as well as allowing me to access my library without having to frequently swap cartridges. Very happy with this purchase, and looking forward to using it again and again!

    Almost Perfect

    Posted by Seth Forsman on Mar 6th 2021

    I purchased the All Region shell for mine, but the fit isn't quite right for a US SNES. When the cart is inserted into the system, the hole in the cart for the peg that lock it in when the power button is switched doesn't line up, preventing powering on the system. This is simply resolved by pulling the cart out slightly, but it feels off. That said, that's the only problem I have with the cart. Otherwise, it's a very amazing product and I am happy with it in every way except the minor annoyance described above.

    FXPAK Pro Classic and Retro Future Deluxe Edition (Japan/Europe)

    Posted by Otto Vaessen on Nov 23rd 2020

    I have ordered two FXPAK Pro cartridges from Stoneagegamer one month ago. A FXPAK Pro Classic and a FXPAK Pro Retro Future. Both in a deluxe edition with light pipes. The two cartridges were delivered to my homeaddress in the Netherlands in a protective storage case and a full color printed manual. It was a pity that Stoneagegamer changed the name of the cartridge from SD2SNES Pro to FXPAK Pro. In addition, the cartridge has difficulty with the SNES game Contra III the Alien Wars (Super Probotector Alien Rebels). In the second field the game freezes and glitters provides a completely black screen. The much cheaper “Super 70 in 1 Game Cartridge 16-Bit MultiCart EUR-PAL” that I bought at a retrogame shop around the corner, could run that game well. Nevertheless, I do give this cartridge the maximum rating of five stars. I do this because these are one of the few MSD flashdrives for the Super Nintendo Entertainment System that can be updated with firmware updates. Many problems can be solved in the future as many problems are software related. In addition this everdrive plays homebrews ROMs. It is region neutral and plays all ROMs from Europe, America and Japan.
