FXPAK Pro (Retro Future)


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, purple anodized screws and a Retro Future-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.

    It does everything I throw at it!

    Posted by Mason on Sep 11th 2021

    I have snes, gameboy, msu1, and even hacked snes games and it loads almost every single one quickly without issues.I was surprised on the quality of the cartridge when I received it and it excelled my expectations. The only gripe i did have was the shipping time. It did take a 3 to 4 months to get here bit totally worth the wait.

    It's dope, kinda expensive but definitely the best on the market for this sort of thing.

    As opposed to some other carts for other systems, this one is literally the best for the SNES

    Posted by Mirza on Sep 10th 2021

    Firstly, the finishing work on the carts, and how nicely the stickers are places (accurately) needs to be mentioned thanks to this site, along with nice color combo with the screws, very nice touch, and thankfully using hex screws instead of strip prone Philips as seen with many other carts. The cart itself is nice and solid without having PCB rattling or what not. StoneAgeGamer also has a convenient light pip addon (if you need to see diagnostic lights from the PCB itself if you're using a solid color like this grey one), along with a microUSB cover to keep things nice and tidy.

    You also get hard-gold contacts on the PCB's pins that contact with the system, ensuring the contacts last longer than real carts themselves if I'm not mistaken due to material choice.

    But as for functionality, this thing basically does it all, and actually out-does what carts were capable of on original hardware. The MSU-1 function upgrade thanks to the new late byuu/Near (RIP) which has been adopted by the designer of the FXPak Pro allows for CD quality (44.1Khz 16-bit uncompressed PCM) audio that you will not find anywhere else to play on original hardware (or things like the Super Nt). A handful of some obscure games remain to be supported by this cart. But that number is lessening according to the main designer who will be adding a chip or two more for support soon. The cart still receives regular firmware updates that incorporate functionality others have helped get going. Things like savestates and such.

    You pay for all this handsomely relatively speaking. But generally speaking, the competition isn't even close. Definitely something even the most stringent SNES collector should get (if only to spare their carts from degradation).

    StoneAgeGamer gets another shout-out for the quick shipping and good packaging, since people can be curious how that fairs when ordering from a new place. And also a convenient deluxe edition case if you want to store or transport this thing with you with a collection of games for download to boot.

    Fantastic Flash Cart

    Posted by Scott Mettlen on Sep 9th 2021

    I am extremely pleased with the FXPakPro. This, combined with a super NT is the perfect "it just works" setup for SNES on a modern TV.

    FX Pak Pro is awesome!

    Posted by Nic Caldwell on Aug 10th 2021

    Works great in my original SNES. Had to use home brew software to enable save state. Pretty easy to do. Save state is not compatible with every game. Often times it will mess up music when loading from save state but the music will fix once you reach a loading screen.

    Great tool.

    Posted by Mark on Jul 24th 2021

    Such a great piece of tech. All my SNES games are located in one cartridge. Also, any snes randomizers I want to play also work flawlessly. The ability to use MSU-1 music packs is also a great addition. The save state feature is amazing as well. You can also do crowd control if you’re a streamer and into that thing. This is a must have for any retro gamer.

    Worth every penny!

    This is an awesome cart with many great features! I’m not sure why I waited so long to purchase. If you’re hesitant to buy it just know that you’re getting your money’s worth!
    Thank you Stone Age Gamer!
