David Amadorl’m not sure this is very well known fact but early Playstation 1 console models had more issues with color banding that later ones, they HW patched in the later PS1 revisions so some games would look different depending on where you played it.
Haijo@[email protected] interesting. i know later models replaced a lot of components with an SOC, earlier models have better audio because the DAC in early models was better than the one in the SOC. the video output on earlier models is slightly blurrier and the disc drives on the later models are more reliable. not sure if the SCPH-550X already used an SOC
