The original, bulky PS2 models went through several iterations (V0 to V11). Early Japanese models used BIOS versions 1.00 to 1.20, which were notoriously buggy but highly valued by collectors. As the console matured, Sony standardized BIOS versions 1.60 and 1.70 for global releases, improving system stability and DVD playback capabilities. The "Slim" Era (SCPH-70000 to SCPH-90009)

Covers Europe, Australia, and parts of Asia. Utilizes 50Hz video outputs by default and features version numbers ending in "EC" or "UK".
