SNEdge SNES & Super Famicom 2-Chip RGB Bypass Mod Kit

The SNEdge SNES & Super Famicom RGB Bypass Mod Kit is an internal video enhancement for original 2-chip / multi-chip consoles, designed to reduce the horizontal smearing and soft pixel edges associated with their RGB output. It helps sprites, lettering and fine outlines appear more clearly defined when used with a suitable RGB cable and display.

Compatible with supported PAL and NTSC SNES and Super Famicom motherboards, this kit covers the CPU-01/CPU-02, GPM-01/GPM-02 and RGB-01/RGB-02 families. PAL operation with the mod has been tested by Retrolize. Installation follows the circuit layout of the individual motherboard.

SNEdge works on the console’s analogue red, green and blue video signals to improve edge definition, helping you obtain a sharper picture from your existing hardware. The result depends on the motherboard, installation, cable and display settings.

The original SNEdge design provides two installation approaches. Sidecar installation retains the original RGB transistors, while full RGB bypass replaces parts of the stock video path and is intended to provide stronger sharpening. Both methods require soldering, with full bypass involving additional component removal and motherboard-specific wiring.

The kit includes the SNEdge main board, Multi-Out QSB, FFC ribbon cable and 10µF SMD capacitors. For an appropriate full bypass installation, the QSB provides the connection at the console’s AV Multi-Out. Power is taken internally from the console.

Use the modified console with an RGB-compatible CRT, monitor or external video processor and a cable suited to its output. A separate RGB-capable scaler can provide HDMI conversion for a modern display. Composite and S-Video can also be retained where supported by the console and correctly reconnected during installation.

SNEdge is based on the open-source project from ThunderTechnologies, with technical information available in the SNEdge project documentation.

Supplied with a 12-month Retrolize warranty, UK delivery and tracked international delivery to supported destinations. Explore our Super Nintendo & Super Famicom parts, mods and upgrades for related products.

Installation & Testing

1. Identify the console motherboard and check the matching installation instructions before removing any components.
2. Test the console, then disconnect its power supply and all external cables before opening it.
3. Install the main board, RGB inputs, grounds, internal 5V connection and required capacitors. Keep RGB input wiring short.
4. For full bypass installation, fit the Multi-Out QSB and FFC ribbon cable using the correct motherboard-specific routing. Complete any additional encoder connections required to retain composite and S-Video.
5. Inspect the installation, check for shorts and test RGB alongside every retained video output before reassembling the console.

Installation References

See the original SNEdge installation instructions. For PAL SNSP-CPU-02 installations, also refer to the PAL installation notes and encoder connection photograph. RGB-series motherboards require their own encoder and output-path checks.

This SNEdge RGB Bypass Mod Kit includes a 12-month limited Retrolize warranty from the date of delivery, covering manufacturing defects and hardware faults arising during normal use.

The warranty covers the supplied kit. It does not cover pre-existing faults in the receiving console, unrelated console components or incompatibility with hardware outside the stated requirements.

Customer-caused installation or removal damage is excluded, including excessive soldering heat, solder bridges, lifted or damaged PCB pads, electrostatic damage, incorrect orientation, short circuits and incorrect supply voltage. Accidental damage, liquid damage and misuse are also excluded where the problem is not attributable to Retrolize products, work or advice.

Check the kit and your console’s compatibility before fitting. Handling, alterations or installation that reduce an item’s value may affect an unwanted-return assessment under the Retrolize Returns Policy. This does not exclude rights concerning faulty or misdescribed goods.

Full Retrolize terms apply. This warranty is additional to your statutory rights, which remain unaffected.

What Does The SNEdge Mod Improve?

It targets the horizontal smearing and soft RGB transitions found on original 2-chip SNES and Super Famicom consoles. Correct installation can produce clearer pixel edges, sharper lettering and better-defined fine detail.

Does It Work With PAL SNES Consoles?

Yes. This kit supports compatible original 2-chip PAL SNES consoles, and PAL operation has been tested by Retrolize. Installation wiring and capacitor positions vary between motherboard revisions, so follow the instructions for your exact board.

Does It Work With NTSC SNES & Super Famicom Consoles?

Yes. Supported NTSC SNES and Japanese Super Famicom motherboards are included within the listed 2-chip motherboard families. Check the full board revision before selecting the installation method.

Are RGB-01 & RGB-02 Motherboards Supported?

Yes. These boards are supported, but their encoder and output circuitry differs from the commonly referenced GPM installation. Use the RGB-series instructions and verify the required output isolation and encoder connections.

How Do I Identify My Motherboard Revision?

Read the full revision code printed on the console motherboard after opening it safely. Codes such as SHVC-CPU-01, SNS-CPU-GPM-02 and SNSP-CPU-02 identify different layouts. The case shape and original region alone are not enough to select the soldering instructions.

What Is The Difference Between Sidecar & Full RGB Bypass?

Sidecar installation retains the original RGB transistors and involves fewer changes to the stock video circuit. Full RGB bypass removes or bypasses parts of that circuit and is intended to provide stronger sharpening. Both require soldering and the correct instructions for the supplied SNEdge board.

Will It Make My Console Identical To A 1CHIP Model?

SNEdge improves the existing 2-chip RGB signal; it does not replace the console’s picture-processing hardware or turn the motherboard into a 1CHIP model. The final picture depends on the console, installation, cable and display.

Do I Need An RGB SCART Cable?

You need a suitable RGB cable and an RGB-compatible display or video processor to use the improved RGB output. Where SCART is used, its components and sync wiring must suit the completed modification. Have the installer confirm the required cable, particularly for PAL hardware.

Can I Use It With An HDMI Television?

Yes, via separate equipment that accepts the modified console’s RGB signal and converts it to HDMI. SNEdge itself does not add an HDMI socket or upscale the picture. A converter accepting only composite or S-Video will not access the enhanced RGB output.

Can I Keep Composite & S-Video?

Yes, where the console supports those outputs and the installation includes the appropriate encoder connections. An RGB-only bypass does not automatically preserve them. Tell the installer which outputs you need before work begins.

Are Installation Tools & Wire Included?

No. The kit contains the main board, Multi-Out QSB, FFC ribbon cable and 10µF SMD capacitors. Soldering equipment, flux, hookup wire, a multimeter and external video cables are separate. Some motherboard revisions may require additional components.

Will It Repair A Faulty Console?

SNEdge is intended as an enhancement for working hardware. Existing capacitor, power or video faults should be diagnosed before installation. It should not be treated as a general repair for a console with no picture or other unresolved faults.

How Quickly Will My Order Be Dispatched?

In-stock kits ready for dispatch are normally sent the same working day when ordered before 2pm UK time, or the next working day after 2pm. Working days exclude weekends and bank holidays. Available delivery services, charges and estimates are shown at checkout.

Is International Delivery Available?

Yes. Tracked international delivery is available to supported destinations. Available Royal Mail services, delivery charges and estimates are shown at checkout. Duties and taxes collected at checkout are shown before payment; otherwise, applicable import charges are payable on arrival.
