Breaking Ground in Retro Gaming Hardware

In an impressive achievement for retro gaming enthusiasts, electronics engineer Lorentio Brodesco has unveiled the nsOne, the first-ever custom motherboard designed specifically for the original PlayStation 1. This groundbreaking mock-up, announced just last week, marks a pivotal moment in the world of classic consoles, being the first of its kind to be developed outside of Sony in the 30 years since the console's launch.

Unlike emulators or FPGA-based clones, the nsOne is a legitimate circuit board that accepts authentic PlayStation 1 chips, seamlessly fitting into the original console casing. This innovation represents over a year of meticulous reverse engineering, sparked when Brodesco discovered incomplete documentation while attempting to repair a PlayStation 1.

Restoring Nostalgia: A Lifesaver for Broken Consoles

For die-hard PS1 fans, the significance of this motherboard can't be overstated. With original PlayStation motherboards becoming increasingly unreliable as they age, the nsOne offers a lifeline. Console owners with damaged systems can potentially revive their gaming experience by transplanting original chips onto this new functional board, avoiding the need to resort to emulation.

A Unique Design and Funding Success

Dubbed "Not Sony's One," the nsOne project employs a hybrid design inspired by the PU-23 series motherboards from SCPH-900X models. Notably, it reintroduces the parallel port that Sony removed in later versions, enhancing functionality for retro gamers. Brodesco upgraded the original two-layer PCB to a sophisticated four-layer board while preserving its classic form factor.

Since its announcement, the project has garnered significant attention from retro gaming communities and tech outlets alike, hitting headlines in notable publications such as Hackaday and TimeExtension. A Kickstarter campaign aimed at funding prototype production and testing has successfully raised over 5,774 euros (approximately $6,684) from enthusiastic backers.

From Repair to Innovation: Inside the Reverse Engineering Journey

Brodesco's journey into the world of motherboard design took a fascinating twist. He began by taking an original PS1 motherboard, painstakingly sanding it down to expose its internal layers. By cross-referencing the traces with available component datasheets and service manuals, he discovered that much of the documentation on the console’s architecture was either incomplete or completely missing.

This revelation set off a comprehensive documentation initiative, where he traced every connection on the board and created multi-layer graphic representations of the circuitry. Employing a mix of optical scanning and meticulous reverse engineering, Brodesco successfully recreated the PlayStation 1 schematic in modern design software, even identifying the exact specifications of components that Sony had never officially documented.

Preserving Gaming History for Future Generations

Brodesco’s vision extends beyond just repairs. His ultimate goal is to create detailed documentation, design files, and production-ready blueprints for fully functional motherboards. By doing so, he aims to preserve the PlayStation 1's unique hardware architecture for future generations, declaring it a tribute to retro gaming and the belief that one individual can indeed achieve the extraordinary.

As we witness this exciting development, the retro gaming community holds its breath, eager for the revival of lost classic consoles and the continuation of beloved gaming experiences.
