EDIT: Okay my bad. Just extracted the newest US ep6 item.sdata and I see now what you've done. It doesn't open in ShStudio/Python because the format of the file is different (like the original Korean before they encrypted it different)
Can still be read in hex and the data transferred into .csv format (or directly to Sdata) like you have done in this release, so my bad
For anyone still wondering what the "point" to this release is.. Those who grab the newest EP6 files (from 2 / 3 days ago) Wont be able to open them with the normal tools any more. So I suggest to stop at patch 200 (I think that would be the one) to grab the "working" ep6 item.sdata.
Sorry for not realising sooner, Bulgaria and nice work on the quick release considering the amount of "****** and grab" work that needs to be done to get all the values
