Engineer creates first custom motherboard for 1990s PlayStation console
Briefly

The nsOne project represents a significant advancement in the realm of homebrew hardware developing for the PlayStation 1. Spearheaded by Brodesco, the initiative emerged from a need for accurate documentation of the console’s internal architecture. This led him to reverse-engineer the original motherboard meticulously, revealing a lack of reliable resources. Brodesco's project not only encompasses detailed schematics and design efforts but also seeks to enable modern adaptations of classic games through innovative optical disc emulators (ODEs), addressing the limitations posed by aging optical drives on original hardware.
The nsOne project emphasizes the importance of documentation and reverse-engineering for preserving and innovating classic gaming hardware like the PlayStation 1.
Brodesco's meticulous approach to understanding the PlayStation 1's architecture reveals insights into a console often regarded as a technological milestone.
