Checking the alternate revisions a little, noticed this for Toushinden S alt revision:
The second revision matrix is GS-9078P-00570A-P1K V.
Do we have a topic where we can report minor additions like this?
edit: tech db says there are 2 versions of Idol Maajan Final Romance R CD2 - one with iso time 02:41:01 and one with 01:56:21, but the site does not list this under alt versions.
edit2: Pro Yakyuu Greatest Nine '97 ver 1.019 matrix is GS-9139P-01491B-P1K
