A dump flagged as "-Extra" often contains and developer comments that were left in the silicon mask. For example, some "-Extra" dumps have revealed text like: "SCPH5500_JAPAN_EXTRA_DRV" or memory addresses pointing to test hardware that never existed in retail.
The PU-18 motherboard inside the SCPH-5500 integrated several previously separate integrated circuits (ICs) into a more streamlined, cost-effective, and cooler-running layout.
