Some Japanese releases take advantage of these features and may even require a specific version (or higher) of the software.
Consumers that were aware of the PlayStation Broadband Navigator were confused as to why it was not included with the HDD Utility Disc.
SCEA's response was always that the PlayStation Broadband Navigator would be released in North America "at a later date."
Ultimately, the Broadband Navigator was never released outside of Japan, as Sony Computer Entertainment switched to only manufacturing the slim PlayStation 2 models, which never supported the HDD and furthermore and later ending the manufacturing of HDD units for the North American region.
Furthermore, Sony Computer Entertainment Europe released the HDD as part of the PS2 Linux Kit in European regions on May 22, 2002.
