Ringcodes

In general, the rule for adding a new line to the ringcodes field is that this should only be done when a new mastering code or mastering SID is present. For PS2, however, there are two exceptions to that rule:

Australia / Europe

Australian releases often share the same mastering code and SID as their European counterparts, but have a unique pattern for mould SID and toolstamp which differentiates them. Where an Australian disc has a toolstamp A00, B00, C00 etc. and/or a mould SID of the pattern IFPI 65xx (compared to the usual IFPI 94xx for EU releases), then this should be added as a separate line.

See http://redump.org/disc/9639/ for an example

Disc with both data & label-side ringcode

There are some cases where specific editions of a PS2 release (Promo Only, Not For Resale / Platinum), have both data and label-side ringcodes. Where these match retail releases, even if the data-side ringcode is identical an entirely new line should be created with a separate entry for the release with both sets of ringcodes.

Serials

For PS1/2, the internal serials are standardized with hyphen (example: SLUS-01234)
