I'm not sure what license this translation was distributed under. Would appreciate a clarification. Aka Creative Commons, GPL, something custom, etc.
I would appreciate if any member of the translation team can get in touch with Kyence to make a clarification on the translation license (the patch license) and distribution/modification/etc terms of use.
Adding this to the first post (along with a download link) would help as well.
In addition, perhaps ask the PSCave admins to add this information to their download page too.
I would recommend using the BPS format rather than xdelta in order to future-proof the patch a bit more and to minimize the size of the patch and the (slim) possibility of having original-copyright-content within the patch itself. The
Floating IPS utility by Alcaro is handy and does both IPS and BPS formats without issues.
EDIT: Seems that it was Hiei and they are someone who was involved in the actual translation itself and posted it over at RHDN. Disregard the PSA but feel free to keep an eye out just in case.
