SNES OVERRIDE
Your console. Your region. Your rules.
Rediscover the joy of playing on a multi-region Super Nintendo, with control straight from your controller and on-screen confirmation. One board brings together the essential features, without adding multiple modules or visible switches to the console shell.

SuperCIC - 50 Hz / 60 Hz / AUTO
A truly multi-region Super Nintendo
Three main modes are available:
50 Hz
Keeps PAL operation when required.
60 Hz
Enables NTSC operation and restores the original speed of games designed for 60 Hz.
AUTO
SNES OVERRIDE detects the region through the cartridge’s CIC Key and automatically adjusts the console’s operation.
Insert your game and turn on the console: SNES OVERRIDE takes care of the rest.
D4 Patch
SNES OVERRIDE therefore includes support for the D4 Patch to improve compatibility with these titles.
The D4 Patch can be enabled or disabled from the controller, and its status is immediately confirmed by the OSD:
D4 PATCH: ON
or
D4 PATCH: OFF
Its state is saved and automatically restored the next time you turn on the console.
IGR - In-Game Reset
This feature saves you from having to press the physical RESET button and is particularly convenient when using flashcarts.
FXPak Pro / SD2SNES
Integration designed for modern SNES flashcarts
Region Pass-Through
This mode lets SNES OVERRIDE follow the region information sent by the FXPak Pro / SD2SNES whenever its operation requires it, while retaining the benefits of SuperCIC.
You can return directly to the flashcart menu:
- From the Player 1 controller
- From the RESET button
Optional status LED
However, thanks to the OSD, installing it is no longer necessary.
Want to keep the traditional light indicator?
Install the LED.
Want to keep the console’s exterior completely original?
Leave it out.
SNES OVERRIDE works perfectly in either configuration.
Settings memory
Your selected settings are automatically restored at the next startup.
Configure your Super Nintendo once: SNES OVERRIDE remembers.

Installation guide
🔒 Important safety instructions
• Work on a clean, stable and well-lit surface.
• Use a suitable soldering iron, flux and a fine tip.
• Always inspect your traces and solder joints under magnification before reassembly.
1. Disassembling your SNES Super Nintendo / Super Famicom
Remember to have a 4.5 mm Security Bit (Gamebit) screwdriver ready: it is essential for removing the security screws underneath the console.

3. Disabling the Nintendo CIC

3.1 Disabling the original Super Nintendo CIC
The procedure simply involves desoldering and slightly lifting certain CIC pins so that they no longer touch their pads.
This method is preferable to removing the component completely: it minimizes work on the motherboard and avoids unnecessarily exposing the CIC and nearby components to excessive heat.
Using a soldering iron with a fine tip, heat each pin individually.
Once the solder is fully molten, gently slide the tip of a scalpel or a very fine tool under the pin, then apply light upward pressure to lift it away from its pad.
Work gradually, one pin at a time.
There is no need to lift the pins very far: a few tenths of a millimeter are enough. The only goal is to eliminate electrical contact between each pin and its pad.
In particular, check that:
- pins 1, 2, 10 and 11 no longer touch their pads;
- there are no solder bridges;
- the lifted pins do not touch adjacent pins;
- no motherboard pads or traces have been damaged.
Finish by thoroughly cleaning the area with isopropyl alcohol (IPA) to remove any flux residue.
The Nintendo CIC remains physically present on the motherboard, but the necessary signals are now isolated.
The motherboard is now ready for SNES OVERRIDE installation and wiring.
4.1 - Preparing PPU1 & PPU2

- SNS-CPU-RGB-01

- SNS-CPU-APU-01
4.1.1 - Preparing PPU1
Then identify pin 24 of the S-PPU1.
Using your soldering iron, gently heat pin 24 while sliding the tip of a scalpel or thin blade underneath it.
Gently lift the pin to isolate it completely from its pad on the motherboard.
Never force the pin: it is fragile and can break easily.
4.1.2 - Preparing PPU2
Identify pin 30 of the S-PPU2.
As before, gently heat the pin with your soldering iron and use a scalpel or thin blade to lift it.
The pin 30 must be completely isolated from its pad on the motherboard.
4.1.3 - Connecting the two PPUs
- Lightly tin pin 24 of PPU1.
- Lightly tin pin 30 of PPU2.
- Use a fine wire, such as 30 AWG or smaller, to connect the two pins directly.
PPU1 - Pin 24 ↔ PPU2 - Pin 30
This connection will allow SNES OVERRIDE to control frequency selection on both PPUs simultaneously.
4.1.4 - PPU 50 Hz / 60 Hz control wire
Then route this wire to the other side of the motherboard through an available through-hole (via) nearby.
This wire is the 50 Hz / 60 Hz control line for the PPUs.
It will connect to point no. 6 on SNES OVERRIDE when you install the module, as detailed in the next chapter.
4.2 - Preparing 1CHIP consoles (S-CPUN / Ricoh 5A122)
Unlike early console revisions that use several separate integrated circuits, 1CHIP motherboards combine the CPU and both PPU functions in a single integrated circuit.

6.1 - Installing the bi-color LED - PAL Super Nintendo / JPN Super Famicom
Bi-color LED pinout
Using your soldering iron and flat-nose pliers, remove the original red LED from the controller port board.
Center lead: + : common positive connection (common anode)
Long lead: RED
LED operating colors
- RED : 50 Hz
- BLUE : 60 Hz
- PURPLE : AUTO
Using flush cutters, trim the center lead to length, then solder it as shown in the following diagram:
Trim the outer leads to length with your flush cutters.
Using fine 30 AWG wire or smaller, connect the LED’s two other leads to the corresponding points on SNES OVERRIDE:
- B : BLUE
- R : RED

8 - FAQ - Frequently asked questions
The SD2SNES / FXPak Pro already applies its own region patch. If the SNES OVERRIDE D4 Patch is also enabled, the two systems may conflict.
Recommended configuration:
- SD2SNES / FXPak Pro: Auto Region Patch ON and SuperCIC ON
- SNES OVERRIDE: D4 OFF
Yes. However, we recommend lifting only the four required CIC pins to disable it while keeping the component in place.
It is nevertheless perfectly possible to desolder and completely remove the original CIC.
