The latest AmiCube prototype built around the Artix-7 FPGA marks a huge leap for Amiga hardware enthusiasts. This new board demonstrates dual HDMI and VGA outputs running in perfect sync, giving users flexibility across both modern and legacy displays. Creator Piotr reveals the latest progress in his evening update, highlighting how much effort went into achieving this new level of functionality.
The project relies on SDRAM to maintain the Amiga’s precise timing and low latency. Every component, from voltage regulation to PS/2 joystick ports, has been designed to meet the architecture’s original demands. Piotr confirms that every connection, LED signal, and port is functioning flawlessly, showing a system ready for the next generation of Amiga-compatible hardware.
Dual Output in Action
The demonstration shows both VGA and HDMI operating side by side without delay or visual mismatch. HDMI delivers crisp digital output, while VGA maintains the analog warmth cherished by retro fans. The board currently uses a DVI signal over HDMI, but Piotr plans to integrate full audio support soon, enabling direct connection to 4K TVs without external mixers.
This combination of HDMI and VGA makes the Artix-7 FPGA implementation especially versatile. Users who prefer analog audio can keep it, while others can enjoy all-digital convenience with audio embedded in HDMI. It’s a design choice that bridges two eras of computing.
Dynamic Scaling for Classic Games
One of the standout features of this update is dynamic scaling. Many Amiga games used only part of the display area due to hardware constraints from the original era. Piotr added a feature allowing users to adjust the resolution in real-time by pressing the Scroll Lock key. Each press zooms the image until the game perfectly fills the screen. This innovation preserves hardware authenticity while improving the experience for modern displays.
The scaling works seamlessly on HDMI, with plans to extend the feature to VGA output. The ability to resize and center gameplay dynamically turns classic titles into fullscreen experiences without altering their character.
Next Steps for AmiCube Development
With USB integration and RTG support planned, the AmiCube project continues to evolve. Piotr hints at future compatibility with PiStorm and real CPU modules, offering even greater flexibility. Power delivery improvements are already underway, ensuring stability for expansions and peripherals.
This milestone positions AmiCube Artix-7 FPGA development as a significant advancement for modern Amiga recreation. Piotr closes the video by thanking the community for their input and encouragement, promising more updates as the project moves toward its final board design.
Retro computing fans will want to watch this full demonstration to see how far AmiCube has come—and where it’s heading next.
