Modder Creates Hybrid PlayStation on a Custom PCB

The original PlayStation, released in 1994, fundamentally altered the gaming landscape by shifting the industry focus toward 3D graphics. Six years later, Sony introduced the "PS One," a miniaturized version of the classic console. While it featured more efficient silicon that ran cooler and consumed less power, it suffered from inferior audio processing capabilities compared to the original hardware. This disparity created a niche desire for a "best-of-both-worlds" console, a challenge that modder thedrew, widely known as Secret Hobbyist on YouTube, has successfully tackled. This hybrid project is the culmination of a rigorous redesign process. In previous chapters of his work, the modder successfully miniaturized the PS One motherboard to about a quarter of its original size. However, that iteration still relied on numerous external components. The latest evolution involves creating a completely custom PCB that integrates the most efficient components from both the PS One and the original PlayStation, aiming to eliminate all hardware compromises. To achieve this, the modder carefully desoldered the CPU, GPU, and RAM ICs from the PS One, which are significantly more efficient. He then sourced the audio chip, CD drive controller, and BIOS from an original PS1 motherboard. These disparate parts were painstakingly resoldered onto a single, tailor-made PCB designed specifically for this hybrid architecture. This level of hardware integration is a significant feat of electrical engineering. Beyond the raw components, the new PCB integrates two critical modifications: an XStation and an HDMI daughterboard from Hispeedido. The XStation replaces the aging CD drive, allowing users to load ROMs directly from a microSD card. Meanwhile, the HDMI modkit utilizes an FPGA to interface directly with the PS1 GPU, enabling high-quality 1080p HDMI output upscaled from the original 480p resolution. This allows the console to look pristine on modern, high-definition displays. During the initial power-on tests, the modder bypassed the need for a 3D-printed shell, using alligator clips to inject power directly into the voltage rails. The results were staggering: the entire motherboard consumes less than 2 watts of power and operates perfectly at 3V. This extreme power efficiency is a testament to the modder's design choices, making the system an ideal candidate for future handheld modifications. In live demonstrations, the console ran various games flawlessly, outputting a clean signal that even included simulated scanlines to mimic a CRT shader. While a few wires remain for the controller and memory card ports, the modder is already working on fully integrating these into the PCB. These minor, temporary quirks do not detract from the fact that the most difficult engineering hurdles have already been cleared. This project sits at the intersection of retro-gaming enthusiasm and modern hardware engineering. Similar to recent community projects like turning a PS4 Slim into a handheld or fitting a full PC inside an Xbox One S, this hybrid PlayStation demonstrates that hardware limitations are often just challenges waiting for the right creative solution. It stands as a stark contrast to commercial efforts, proving that individual enthusiasts can often achieve levels of integration that original manufacturers did not prioritize at the time. As the project nears completion, it serves as a reminder of the vibrant modding scene that continues to push the boundaries of legacy hardware. By combining the superior audio of the original unit with the power efficiency of the PS One, Secret Hobbyist has created a device that is arguably the ultimate version of the 1994 classic. Whether it eventually finds its way into a custom handheld chassis or remains a desktop board, this hybrid PlayStation is a significant milestone in console preservation and modification.
