The original SNES release of Star Fox has received a hardware-level performance upgrade, swapping its aging polygon co-processor for a brand-new Super FX 3 chipset designed by engineer Randy Linden. According to Time Extension, the modified cartridge is now able to sustain its maximum frame rate far more reliably than the 1993 retail release, turning one of Nintendo’s most beloved shooters into a noticeably smoother experience for retro collectors.
Time Extension reports that the upgraded build is, as the publication put it, able to “hit the maximum 20fps far more often than before.” The new Super FX 3 silicon traces its lineage to the same chipset family that powered Limited Run Games’ recent re-release of the SNES DOOM port, continuing a growing trend of modern engineers reviving and refining Super Nintendo enhancement chips for today’s homebrew and modding communities.
Why This Matters For Retro Fans
For longtime Star Fox players, frame pacing has always been part of the game’s charm and frustration. The original cartridge was already a technological marvel for its era, but its polygon-heavy levels often dipped well below the console’s ceiling during intense Arwing dogfights. A mod that brings the experience closer to a locked 20fps target is the kind of tweak that preservation-minded collectors and arcade-style completionists have been chasing for years.
It also signals something bigger: Super FX silicon is becoming a living platform rather than a museum piece. Each new generation of the chip builds on Argonaut’s original architecture, and hobbyists now have more reason than ever to crack open their carts, study the boards, and experiment with drop-in replacements. For retro enthusiasts who treat their SNES hardware like a tuned arcade cabinet, that opens the door to a wave of community-driven speedruns, comparison videos, and preservation projects.
The Road From Super FX To Super FX 3
Background: the original Star Fox, released in 1993 and developed under the direction of Shigeru Miyamoto, was the first SNES title to use Argonaut’s Super FX chip, a dedicated RISC processor that handled the 3D math the console’s main CPU could not. The chip famously powered a brief wave of polygon-driven SNES releases, including Stunt Race FX, Doom, and the later Super FX 2-equipped Yoshi’s Island. Each iteration improved throughput and effects, but supply constraints and cartridge costs kept the lineup short.
Randy Linden’s Super FX 3 carries that torch forward, and its earlier deployment in a modernized SNES DOOM cartridge established it as a viable platform for contemporary homebrew publishers. Slotting it into Star Fox feels like a natural fit: the game is the franchise’s definitive origin point and the title that put the Super FX name on the map. Smoothing out its frame rate doesn’t just improve one game, it makes a strong case that the entire Super FX library could benefit from similar treatment.
For collectors watching this space, the takeaway is simple. Keep an eye on the RetroArcade news desk for further Super FX 3 developments, because the same hardware that just gave Arwings a smoother ride may soon be heading to other SNES classics.
