Amiga Retro continues exploring the HD-64 True HDMI adapter for the Commodore 64 in Part Two of the series. This new episode focuses on installation, jumper setup, and user configuration, showing how this adapter transforms video output into a clean HDMI signal.
The video begins with a look at hardware preparation. The host explains jumper settings for both longboard and shortboard C64 models. Longboards need external 5V wiring, while shortboards draw power directly from the modulator header. Each adjustment is shown clearly on camera, helping viewers complete the process with confidence.
Next, Amiga Retro demonstrates how to configure the board. The video covers chroma settings, audio options, and LED indicators that confirm proper voltage and signal. Once the HD-64 True HDMI is in place, the video moves to the software configuration utility. Using an Ultimate 2+ cartridge, the host shows how to change visual settings, including blur, scanlines, and scaling.
Each change updates in real time. The scanline depth and width can be adjusted easily, and the video mode can switch between RGB, DVI, and YCCC. The RGB setting provides both video and audio over HDMI, making it the preferred choice. Users can also adjust zoom to remove screen borders or tweak the color palette to match personal taste.
After saving the configuration, the results are immediate. The HDMI signal looks clean and stable with no distortion or flicker. The host confirms that settings persist after power cycling, which means no need to reconfigure each session.
The episode concludes with a C64 demo scene presentation titled 1991, showing the system’s full HDMI output in action. For Commodore 64 enthusiasts, Amiga Retro’s walkthrough offers a clear, helpful, and visually engaging guide to the HD-64 True HDMI.
