Early PlayStation units (SCPH-1000/3000/1002) relied on a physical mechanism for region locking: the placement of the CD drive lid sensors. Consoles checked if the lid was opened or closed to verify disc swaps. The Version 3.0 BIOS found in the 5502 unit introduced a shift toward software-based checks. While the physical sensors remained, the kernel logic was rewritten to be more robust against the "swap trick" methods that plagued earlier models.
However, this evolution also introduced compatibility quirks. The earlier BIOS versions contained a specific bug that unintentionally allowed certain bootlegged discs to run. The 5502 BIOS patched this vulnerability, meaning that some unlicensed "backup" methods that worked on launch units failed on 5502 units. Conversely, the 5502 BIOS offered better memory card management stability, addressing the dreaded "Block Free" corruption issues that plagued early PAL adopters. Don't trust file names
