Most original NES controllers haven’t seen active duty in decades. They survive in storage bins and attic boxes, physically intact and perfectly functional as controllers, but with nothing left to plug them into. The consoles they were paired with have long since been replaced or decommissioned. The hardware was always well built, but the form factor has been sitting idle for years.

This mod changes the job description of that controller shell entirely. The electronics inside a standard NES-style gamepad were stripped out and replaced with a Wemos ESP32-S2 Mini development board, a 1.54-inch 240×240 TFT display, a MicroSD card module, a 500 mAh lithium-polymer battery, a charging board, a speaker, and a slide power switch. From the outside, it still looks exactly like an NES controller.

Choosing the right processor was essentially a geometry problem. A larger ESP32-S3 would have offered dual-core performance and enough PSRAM to keep entire game ROMs in memory, but it was too big to fit inside the housing. Smaller ESP32 variants without PSRAM lacked the memory for smooth emulation. The ESP32-S2 Mini landed in the narrow window between board size and processing capability that the build required.

Getting everything to fit required real surgery on the shell. Internal plastic supports had to be trimmed back to make room for the display, and new openings were drilled for the screen, USB charging port, MicroSD slot, speaker, and power switch. A bare copper wire serves as a central ground distribution rail, cutting the number of individual ground wires needed and making it possible to actually close the controller afterward.

On the software side, the device runs the Retro-Go emulator framework, compiled using ESP-IDF and CMake since the ESP32-S2 isn’t a standard Retro-Go target. The result handles a range of classic 8-bit systems comfortably. As a bonus, Doom runs via PrBoom-Go from a Freedoom WAD file loaded on the MicroSD card, managing somewhere between five and 15 frames per second depending on the scene.

The total build cost runs about $17 using common suppliers, or closer to $8 when sourcing directly from overseas markets. That puts the project well under the price of a single modern game release. Flip the power switch, select a ROM from the MicroSD card, and the screen loads games that once required a dedicated console and television setup. No additional hardware is needed.

What makes this more than a novelty is how it reconsiders a form factor most people already have muscle memory for. The D-pad clicks the same way it always did, and the A and B buttons carry the same spring. What changed is where the signal goes after the press. Instead of traveling to a console that no longer exists, the controller now processes it directly inside its own shell.

The Retro-Go framework is open source, the parts are widely available, and the NES controller shell is one of the most common pieces of vintage hardware still circulating through the secondhand market. Nothing about this build required specialized equipment or proprietary components. The total part list costs less than a single new game on any current platform and fits inside hardware that most people already own.

The retro handheld market has a strange problem. The hardware keeps getting better, the screens get sharper, the processors get faster, and yet most of these devices land looking like prototypes someone forgot to finish. Generic shells, forgettable proportions, and LED lighting as a substitute for actual design thinking. For a category built entirely on nostalgia, very few of these devices actually look like they belong to any era at all.

That tension is what one Reddit user decided to address. Starting with a Retroid Pocket 5, a $199 Android handheld running a Snapdragon 865 and a 5.5-inch AMOLED display, the mod layers Sony and Nintendo branding onto the same shell. Vinyl decals, translucent polycarbonate, a 3D-printed volume rocker from Etsy, and a cable replaced in PS2 color. The result looks less like a sticker job and more like a concept render from an alternate 1999.

The translucent shell is doing most of the work. It pulls from the visual language of the N64’s Funtastic series, those clear and atomic-purple controllers Nintendo released in the late 1990s, where showing the circuitry was the design choice rather than concealing it. Over a piano-black grip body with PlayStation-colored face buttons, the frosted polycarbonate shifts from grey to near-white depending on the light. It shouldn’t feel considered. It does.

The branding placement is where intent becomes clear. The Sony wordmark sits centered on the upper face, exactly where it appeared on a PSOne. Below it, the PlayStation four-color logo. At the bottom bezel, the Nintendo badge mirrors its position on a Game Boy Advance SP. None of it is licensed, of course. These are adhesive vinyls placed by someone who grew up with both systems and wanted their coexistence on one device to feel inevitable rather than absurd.

Not everything here reaches backward. The analog sticks are translucent caps over hall-effect sensors, lit teal on the left and purple on the right, owing nothing to 1999. That generation didn’t have RGB anything. The lighting reads as a concession to the present; the one feature announcing this is still an Android device in 2025, not a prototype from some alternate Sony-Nintendo licensing meeting. Whether it sits comfortably alongside the retro shell is a fair question.

The rear view shifts the frame again. A large dual-grip body in smooth black rubber dominates the back, a clear plastic hinge connecting the screen to grip in full view, structural and unapologetic. The 3D-printed volume rocker at the top edge puts a physical control where fingers naturally land. The back half feels closer to a DualShock than a Game Boy, which is either the point or the problem, depending on what you wanted this thing to be.

Flip to the front screen, and the emulator grid makes the whole thing literal. DuckStation for PS1, Dolphin for GameCube, PPSSPP for PSP, melonDS for Nintendo DS, and a live PS2 wallpaper cycling behind all of it. This device runs both companies’ libraries simultaneously without asking permission from either. The branding on the shell, in that context, stops being a novelty and starts reading as a plain statement of what the hardware already does.

The retro handheld category is large enough now that sameness has become its default. The Retroid Pocket 6, the current flagship from the same manufacturer, drew community criticism for being indistinguishable from competitors: glass front, LED sticks, rounded edges, and no particular character. A fan mod building identity out of borrowed logos is one response to a problem the manufacturers haven’t solved. It’s also just someone enjoying a hobby and being honest about what they want.

The hardware to play PS1, PS2, GameCube, and Game Boy Advance all on one screen already exists and costs under $200. What the market hasn’t resolved is what that device should actually look like, or whose name should go on it. This mod doesn’t answer either question. It just makes the gap between what’s technically possible and what anyone has bothered to design feel a little harder to dismiss.
