  • 3.2: CXD2955R (GH-026, GH-027, GH-029, GH-032, GH-035)
    • Additionally also includes functionality of SPU2

Starting with GH-026, the SSBUS controller and the SPU2 were combined into a single chip (CXD2955R), until the SSBUS controller ultimately became obsolete with the introduction of the L-chassis (SCPH-750XX). From a software viewpoint, these newer consoles report a v3.1 SSBUS controller.
