SNES Edge-Enhancer Mod by Voultar Offers Complete Video Upgrade for 2CHIP Consoles

The Super Nintendo Entertainment System (SNES) remains one of the most enduring platforms in gaming history, with a vibrant community devoted to preserving and enhancing its legacy.

Over the decades, multiple hardware iterations of the SNES have led to variation in video quality, particularly between the 1CHIP and 2CHIP models.

With the latter often criticized for their softer and blurrier visuals, dedicated enthusiasts have sought new solutions to bring their classic consoles up to modern standards.

Now, renowned hardware engineer Voultar has delivered a game-changing upgrade for the 2CHIP SNES with his newly finalized SNES Edge-Enhancer mod. Announced on July 3rd, 2024, Voultar confirmed via social media that the SNES Edge-Enhancer is complete and production-ready.

"The SNES Edge-Enhancer is finished," Voultar stated in a public update, underscoring that the time and effort invested have resulted in a robust, final production prototype.

He emphasized the breakthrough performance achieved by optimizing the 2CHIP SNES digital-to-analog converter (DAC), ensuring the best possible output for the aging hardware.

The device now delivers crystal-clear Composite Video (CVBS) and S-Video output, providing a level of sharpness previously thought exclusive to software emulation. A recent video by the respected retro gaming channel My Life In Gaming showcased the SNES Edge-Enhancer in action, revealing the noticeable improvement in video clarity when compared to the standard 2CHIP output and RGB bypass mods.

Retro RGB has also published comprehensive resources detailing the differences between SNES hardware revisions, illustrating why enthusiasts have been eager for such a mod. The SNES’s legacy is intertwined with its various hardware changes.

Early releases, including both the Super Famicom and North American SNES, utilized a two-chip video processor design, frequently criticized for producing a somewhat blurry analog signal.

Nintendo improved upon this in 1995 with the introduction of the single-chip, or "1CHIP," models—now widely regarded as the gold standard for SNES video quality.

Owing to their superior clarity, 1CHIP models command a premium in the retro gaming market. Voultar’s SNES Edge-Enhancer specifically addresses the visual shortcomings of the more common 2CHIP SNES units.

Drawing on extensive research, Voultar reverse-engineered the SNES DAC—relying not on community forums but on close hardware analysis using chip die shots to pinpoint and solve the inherent issues.

Voultar confirmed, "I meticulously examined the SNES DAC’s internal structure to understand and resolve the video sharpness issues unique to 2CHIP systems." The installation process remains approachable for those with soldering experience, requiring only a simple five-wire connection compatible with all 2CHIP SNES revisions.

Voultar stressed ease of use and broad compatibility: "It’s five wires—a straightforward install for nearly any 2CHIP SNES—and ensures improved visuals across all video outputs." Distinct from many aftermarket solutions, the SNES Edge-Enhancer does not rely on amplifying or artificially sharpening the video signal via low-pass filtering.

Instead, the mod maintains uniform enhancement for all video outputs—RGB, S-Video, and Composite—across any content rendered by the SNES Picture Processing Unit (PPU).

Voultar explained, "My approach ensures that the mod delivers consistent sharpness for all video output types, rather than relying on content-dependent enhancements." While the Edge-Enhancer dramatically improves sharpness, Voultar cautions that it should not be seen as a universal fix for all SNES video noise.

He shares, "Multiple factors cause analog video noise on the SNES.

I am also developing complementary mods to further address these issues." Affordability is another central focus; Voultar has kept manufacturing costs down, targeting a retail price of approximately $100.

"This mod is my love letter and farewell to the SNES," Voultar remarks, expressing his ongoing commitment to the retro gaming community. With the SNES Edge-Enhancer, enthusiasts now have access to an expertly-engineered solution that brings their treasured 2CHIP SNES consoles much closer to the clarity of their sought-after 1CHIP counterparts—preserving, and even improving, the classic Super Nintendo experience for years to come.
