FXPAK Pro (Base)


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 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.

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.


  • FREE DIGITAL GAME: Blow 'em Out
  • 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.

    Versatile but enhancement chips can be glitchy

    Posted by Not2Tired on Nov 7th 2021

    Easily run almost every SNES game, and lots of GB & GBC games once the proper firmware is in place. The menu is user-friendly, and can be customized with the help of easy-to-locate online walkthroughs. Save states and other triggers/hooks can be set, although there are some limitations for certain games - although these limitations are not the fault of this product - the SNES controller simply doesn't have a lot of extra buttons. I love being able to quickly and easily play my entire SNES and GB collections on my TV! The biggest concern I have is that many enhancement chip games have small slivers or panels that flash for a frame or two. It can be distracting, though the games remain playable. These graphical artifacts went away when I used an original cartridge, so I am confident it is this product causing the glitches. Overall, I highly recommend this product, but you should get original carts for enhancement games you want to be 100% sure will display perfectly.

    FXPak Pro

    This is by far the best solution for playing ROM-hacks on the original Hardware. The firmware development ist still active and more functions are getting added. Definitely worth the price.

    The best thing ever made and the greatest SNES experience had from this exact flash drive. Purely one of the flash carts to get. Extremely recommended. 11 out of 5 stars.

    Modern Solution for Vintage Problem

    Posted by BigPep243 on Sep 28th 2021

    I purchased this to pair it up with my Analogue Super NT and this is the best. I like how I do not have to swap out cartridges anymore since I have all my cartridges in one cartridge. If you own an OG SNES or a clone that you would like to have all of your cartridges in one cartridge I recommend this one. I have had no issues it does what it is advertised and I got mine with the case so its protected when I have it put up. But, when you have one of these there is no sense in swapping out cartridges anymore just leave this sucker in and game it up.

    Great product that's still a work in progress

    Posted by nbuubu on Sep 10th 2021

    Roms load very fast, and MSU-1 versions of my favorite games make them feel new again with high-quality sound. Using mine with both my rgb-modded SNES Jr, and SuperNT, and it's flawless.

    New features are still being added, with save states (working well but still somewhat buggy as of September 2021) and hopefully a cheats menu coming in the near future. Highly recommended.
