Sony released this as a 'mod-proof' system, but was cracked pretty quickly (of course!). More motherboard reductions, revised system BIOS. System now came with one Dual Shock (SCPH-1200) controller, and now featured a light show program called SoundScope in the CD player menu (this was actually a stripped-down version of Baby Universe). SCPH-7000 - First Japanese 'Dual Shock' hardware revision. SCPH-5903 - Special white-colored 'Video CD' edition of the PS, released only in greater Asia. SCPH-5502 - European version of the 5500. SCPH-5501 - North American version of the 5500. CD drive mech was relocated, onboard electronics shortened by ~20 percent, seperate ports for A/V composite output were replaced by the A/V Multi Out port.
