Hadoken! Build a custom arcade-style USB fightstick in a 3D printed case using an Adafruit KB2040 board and GP2040-CE firmware. You can use it to play games on consoles, such as Switch, PlayStation, and Xbox, as well as Raspberry Pi-based RetroPie emulators and PC/Mac/Linux computers.
This joystick and arcade buttons are just the start -- you can add NeoPixel LEDs for dramatic, per-button lighting effects and an OLED LCD screen for settings and diagnostics.
