Elevate your classic gamepads to USB capabilities with Reflex CTRL! Boasting the quickest response times of any USB controller available commercially, Reflex CTRL all but eliminates dropped inputs. Featuring the highly versatile, upgradeable, and customizable GP2040-CE firmware, your gaming will never be the same!

How it works

CTRL boards are PCB replacements with a short USB-C female pigtail cable. Unscrew your controller, remove the OEM circuit board, optionally replace the rubber membranes (coming in 2024?), fit the Reflex CTRL PCB, route the USB-C Female cable, and re-assemble the controller. Users provide their own USB-C cable. 



    • Open-source, powered by the amazing GP2040-CE
    • 0.8 ms latency
    • Carbon-coated button pads (just like OEM) for consistency and durability
    • ESD protection for all inputs
    • Web GUI for deep customization
    • Update firmware: Enter Web GUI > Reboot > USB (BOOT SEL)





      Basically the same as SNES. Don't route the cable through the posts. Route it directly 

      Virtual Boy

      Do not plug the battery or DC power packs into the controller. The controller is powered over USB.


      Take care when closing the controller. The white cable connector may press against the back shell. Shoulder buttons are tactile, not microswitches. Microswitch buttons aren't easy to find. Tested in Japanese controllers, USA model 2 controllers, and Retro-bit licensed wired controllers.

          Here is my long-overdue review of the SNES/SFC Reflex Ctrl. I absolutely love this board. It's my new go-to for using my favorite Super Famicom controller across various platforms, including MiSTer, PC, and Steamdeck. This controller is perfect for playing my favorite 2D platformers, whether they're new or old. I can't express enough how much I enjoy using a modern USB-C cable, which, along with incredibly low latency (less than 1ms), makes the experience seamless. Best of all, it's dongle-free! The Reflex Ctrl also offers a simple web GUI that allows you to customize your buttons and save your settings across all platforms directly to the board! It doesn't get any easier! Did I mention it can emulate a left or right analog stick for games frustratingly lacking d-pad support? Yeah, it's got that too. And switching modes is a breeze—just use a button combo, no need to access the web GUI. Overall, I give the SNES/SFC Reflex Ctrl 5 out of 5 stars. Given its price and rich feature set, I'll definitely consider purchasing more in the future.

          Picked up the Genesis and Virtual Boy CTRL

          I just got done swapping out boards and giving it some play time. For the Genesis, I used a clear blue Retro-Bit 6-button pad as the host. What's cool is that there is a little white LED inside that gives you affirmation that a button has been pressed that you can see with a clear case. The Virtual Boy also went on well, and the red PCB was a nice touch. Both are working perfectly, and I'm excited to try out the virtual boy controller on all kinds of non-analog twin stick games, like Xeno Crisis, as well as Virtual Boy emulation!

          Probably the best way to use an SNES controller over USB

          Its an easy installation and works great. I confused myself a little on the initial firmware setup but it's been very easy since then. Being able to switch between Xinput/Dinput/Switch modes very easily is very convenient and I like the design with the short connector cord, pairs well with the braided USB A to C cables sold here. Eagerly awaiting the Genesis version.

          An exciting reflex product!

          This conversion kit is the real deal. Installation on one of my spare Super Famicom controllers took no time, and it worked right out of the gate with the MiSTer, no fiddling required. I know there is a miniscule difference compared with SNAC/SNAX, but I honestly can't tell. The feel of an original controller with the ability to engage with MiSTer's OSD is pretty great. I can't wait for other Reflex CTRL devices to be developed and released!

          SNES and beyond.

          Love the product. The SNES Ctrl is well constructed and works as intended. Would highly recommend to anyone who loves their SNES controllers and wants to use them with multiple systems.
