| A picture from the PlayStation 2 Portable handheld project |
A solo builder known as Tschicki has done what many thought was impossible: creating a truly custom, handheld PlayStation 2 from scratch. No emulation. No off-the-shelf parts. Just raw engineering, soldering, and a whole lot of patience.
If you grew up with the PlayStation 2, you already know it holds a special place in gaming history. The library alone—Shadow of the Colossus, God of War, Final Fantasy X, Metal Gear Solid 3—is legendary. But playing those classics on the go has always meant relying on emulation, with its quirks, input lag, and occasional glitches.
Enter Tschicki, a solo modder and hardware builder who decided to take a radically different path. Instead of cramming a stock PS2 motherboard into a 3D-printed box, they reverse-engineered the console’s core logic and built an entirely new mainboard. The result? A sleek, powerful, surprisingly premium DIY PlayStation 2 portable that draws ergonomic inspiration from the Asus ROG Ally—while being anything but a mass-produced device.
A Project Two Years in the Making
Tschicki first began work on this portable PS2 back in early 2022. The design went public last year, but this week the project has exploded in popularity as retro gaming communities and hardware tinkerers finally grasped what made it so special.
The handheld’s outer shell clearly takes cues from Windows-based gaming handhelds like the ROG Ally and Steam Deck. You get rounded grips, shoulder buttons positioned for comfort, and a centered screen. But inside, it’s a completely different beast.
The World’s First Custom PS2 Motherboard (That Isn’t Made by Sony)
Here’s where things get mind-bending. Most portable PS2 mods start with a donor console. You desolder components, trim the board, and try to fit everything into a smaller case. Tschicki threw that playbook out the window.
*“This portable contains, presumably, the world’s first custom reverse-engineered mainboard not made by Sony. It only reuses six ICs from an original PS2, salvaged from SCPH-7900x or SCPH-9000x mainboards.”*
That’s right. Nearly every component on the board is brand new. Only six integrated circuits are harvested from an actual PS2 Slim. Everything else—traces, power regulation, video output, audio processing—was designed from the ground up.
Crisp Video, Modern Connectivity, and DualShock 2 Rumble
One of the biggest challenges when modernizing the PS2 is its native interlaced video output. On a crisp LCD panel, those interlaced signals can look jagged or blurry. Tschicki solved this with a Trion T20 FPGA, which handles digital video processing including:
- Motion-adaptive deinterlacing
- Line doubling
- Bilinear scaling
The result is a clean, sharp image that retains the original game’s look without the usual flicker or combing artifacts.
Power management is handled by an RP2040 microcontroller—the same chip found in the Raspberry Pi Pico. The RP2040 doesn’t just regulate voltage and charging; it also emulates a full DualShock 2 controller, including analog face buttons (yes, pressure-sensitive inputs work) and even old-school rumble.
Battery Life That Rivals Modern Handhelds
Two 21700 lithium-ion cells provide roughly 4.5 hours of playtime, depending on the game. That’s genuinely respectable for a device built from scratch. Charging happens over a standard USB-C port, and Tschicki implemented an undervolting configuration to keep thermals under control during extended sessions.
Premium Feel, DIY Reality
Despite being a one-person garage project, the finished portable looks remarkably polished. Photos show a clean white shell with PS Vita-style face buttons (including the colored PlayStation symbols) and Hall-effect analog sticks—meaning no drift, ever.
But don’t let the sleek photos fool you. Tschicki is brutally honest about the difficulty level. In the project’s GitHub repository, every PCB design, FPGA code, 3D-printable shell file, and firmware binary is available for free. However, the warning is clear:
“I would highly recommend not building one, even if you know what you are getting yourself into.”
This isn’t a weekend soldering project. You’ll need fine-pitch BGA soldering skills, a chip programmer, and the ability to debug obscure hardware issues. The BGA work alone—reflowing those six salvged ICs onto a custom board—is beyond most hobbyists.
What About Just Buying a PS2 Instead?
Of course, not everyone needs a portable PS2 built from reverse-engineered parts. Sometimes the simplest path is the best one: pick up a renewed original console, plug it into a TV, and play your old discs.

Why This Matters Beyond Gaming
What Tschicki has accomplished goes far beyond a cool YouTube project. By reverse-engineering the PS2’s motherboard and publishing all the files open-source, they’ve created a blueprint for preserving gaming history. Original PS2 hardware is aging—capacitors fail, lasers die, and Sony stopped production years ago. A custom board that reuses only six key chips means the console’s soul can live on even as original parts become scarce.
The use of an FPGA for video processing is particularly forward-thinking. As display technology evolves, having programmable logic to handle scaling and deinterlacing ensures this portable will remain usable for years.
The Bottom Line
- Who is it for? Elite hardware hackers, reverse-engineering enthusiasts, and anyone with a reflow oven and too much free time.
- Who is it not for? Pretty much everyone else. Tschicki isn’t selling completed units. You build it yourself, or you don’t get one.
- What’s the coolest part? The fact that it exists at all. A single modder reverse-engineered Sony’s most successful console, built a brand new motherboard, and made it fit in a handheld shell that looks like it could sit next to a PlayStation Portal.
For the rest of us, there’s always the renewed original hardware or—for the brave—a deep dive into Tschicki’s GitHub repo.
All design files, FPGA code, firmware, and 3D models are available here.
Whether you’re inspired to build one or just happy to admire from afar, this project proves that the PS2’s legacy is in good hands—even if those hands are covered in solder.
