We spend a lot of time talking about the premium hardwood and genuine arcade parts that make up the physical chassis of a stct8r arcade stick. But a beautiful controller means nothing if the internal brain can't keep up with your inputs.
Every stct8r controller is powered by an RP2040 Advanced Breakout Board running the industry-leading GP2040-CE open-source firmware.
If you aren't familiar with custom arcade stick hardware, you might be wondering what that actually means for your gameplay. Here is exactly how it works, what systems it plays on, and how you can customize it.
The Need for Speed: Sub-1ms Latency
In fighting games, a single frame of delay is the difference between blocking a mix-up and eating a full combo.
GP2040-CE was built from the ground up by the fighting game community for one specific purpose: speed. By utilizing the dual-core RP2040 processor, the firmware dedicates an entire core strictly to reading your button presses. The result is a highly optimized, overclocked 1000 Hz polling rate that delivers an average input latency of less than 1 millisecond. It is mathematically one of the fastest controller boards on the market today.
Out-of-the-Box Compatibility
We ship every stct8r pre-flashed with the absolute latest GP2040-CE firmware. That means the second you pull it out of the box, it is native "plug-and-play" on the following platforms without needing any extra software or adapters:
-
PC (XInput & DirectInput)
-
Steam Deck
-
Nintendo Switch
-
PlayStation 3
-
Android
Playing on PlayStation 5, PlayStation 4, and Xbox Series X|S
Modern consoles like the PS5 and Xbox use strict security handshakes to verify that a controller is "official." If a custom arcade stick doesn't answer that handshake, the console will disconnect it after 8 minutes.
To solve this, every stct8r board is built with a dedicated USB Passthrough Port. Instead of hacking the console, the GP2040-CE firmware uses a perfectly legal, tournament-approved bypass. You simply plug a small authentication dongle (like a Mayflash MagicBoots v1.1 for PS5, or a Brook Wingman) directly into the internal USB port on your stct8r. The firmware routes the console's security handshake through the dongle while routing your lightning-fast inputs through the main board.

Do I need a dongle? Only if you plan to play natively on a PS4, PS5, or Xbox Series console. For PC or Switch players, you can ignore the port entirely!
Total Control: The Built-In Web Configurator
We hate bloated background software just as much as you do. You do not need to download any sketchy apps or drivers to change your button layouts.
The GP2040-CE firmware features a built-in Web Configurator. If you hold down the START button while plugging your stct8r into your PC, the controller essentially acts as its own mini-website. You just open your web browser, type in a local IP address (usually 192.168.7.1), and you gain instant access to:
-
Remap any button.
-
Change your SOCD cleaning rules (Neutral, Up-Priority, Last Win).
-
Adjust LED colors and patterns.
-
Update to future firmware releases.
Where to Learn More
Because GP2040-CE is an actively updated, community-driven project, new features and optimizations are added constantly. If you want to dive deep into the technical documentation, check out custom wiring diagrams, or learn advanced web-configurator tricks, you can read the official documentation at gp2040-ce.info.
When you buy a stct8r, you are getting the pinnacle of open-source fighting game technology, housed in an heirloom-quality shell.
