I remember hearing about an options menu in 3s to unfix some of the fixes that were put in on the dc version. Does this exist? What are the default settings? Are people changing the defaults in their version?
I believe you are referring to the unblockables which were disabled on DC. On PS2, they can be turned on or off via the ‘Guard Judgment’ option. By default, I believe it is set to ‘Old,’ meaning the unblockables are enabled (a la arcade).
