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.

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.


  • microSD supported (tested up to 64GB; no exFAT support so SDXC cards must be reformatted using FAT32).
  • Fast ROM loading (~9MB/s).
  • Fast menu navigation.
  • Directories are sorted automatically, no need for FAT sorting tools.
  • High resolution menu (512×224) for adequate display of long file names.
  • Real Time Clock.
  • Supports ROM size up to 128MBit (96Mbit actually implemented).
  • Automatic near-time SRAM saving to SD Card (while the game runs). Some limitations apply:
    • near-time saving is switched to periodic saving when a game is found to use the SRAM as work RAM.
    • Automatic saving is disabled when MSU1 is used. SRAM is saved on reset.
    • Enhancement chip support (see below for implementation status).
  • SuperCIC key (SNES CIC clone):
    • enables operation on unmodified consoles of all regions.
    • supports software 50/60Hz switching on SuperCIC enhanced consoles only (to be performed by FXPAK firmware, not yet implemented there).
    • Auto region patching: eliminates “This Game Pak is not designed…” messages regardless of 50/60Hz setting.

    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!

    The best SNES flashcart, hands down!

    Posted by Tony Sakich on May 11th 2021

    I purchased the FXPAK Pro as an upgrade to my Super Everdrive and it was worth every penny!

    The menu selection is an awesome upgrade and the improve compatibility means I now have access to dozens of games that I didn't before. There is no better way to access the Super Nintendo & Super Famicom libraries using original hardware than this flashcart!

    A must have!

    Posted by Joseph DuVall on Apr 12th 2021

    This cart is a must for anyone who owns a SNES! It's compatible with nearly the entire library of games, including enhancement chip games like Star Fox and Mega Man X2.

    While the hardware itself is second to none, the packaging from Stone Age Gamer is excellent. I purchased the Deluxe Edition, where I received the case and extras. The case is like a vacuum-formed plastic that is surprisingly durable and neatly holds the manual and stickers that come with it. Very happy I went with the extras.

    If you're even remotely on the fence about this, purchase it. You won't be disappointed.

    I haven’t put the controller down since I received this! Everything just’s hard to explain. The difference between playing snes on an emulator vs w/ everdrive and original hardware (including component cables) is night and day. I couldn’t recommend it more!

    This thing plays near 100% of the SNES, GB, and black cart GBC libraries. Also, Earthbound is too expensive, and emulators are lame.

    Best in Show

    Posted by Unknown on Sep 7th 2020

    Better than anything else I've seen. Having near 100% compatibility with the entire game library. Puts it well ahead of others. Shell is well designed & Krikzz has done a great job with this flash cart/PCB. Only thing I think could improve it is a cart passthrough. I previously used a Super UFO Pro 8 due to enhancement chip misinformation online. Only allows playback of the cartridge ROM not translations requiring enhancement chips. The only truly useful thing about the pastrough is ROM dumping & SRAM read/write access. A feature I do miss for battery replacement procedures.
