Doing some major digging I came across some old posts from 2020 form trophy hunters sharing saves to unlock each trophy since it was before the Directors Cut theres zero progress on DLC and the last save to "unlock platinum" has pretty much all of the game beat and was at the final fight with the "end boss" and while it wouldn't work initially since its so old (it would just crash the PC ver.)

I converted it back to PS4, Signed it with my account, went offline loaded it with my PS5, saved it fresh with the most up to date PS4 copy then transferred back to PC and converted again to make it work with the PC version....whew!!

So for anyone wanting to jump back in after completing the game on PS4 but never really touching anything after here's a good file to go with.

I made a couple saves myself and included them all in the zip...

manual_0004.sav gets you where they got me... at the last Haiku
manual_0005.sav lets you skip that but still get the final cutscene before battle for the build up
manual_0006.sav gets you straight into the fight no cutscenes if you want to replay it
manual_0007.sav lets you make the "final choice" so you can get your favorite gear set at the end (your choice but I'm a "white" guy myself)
manual_0008.sav will get you past all that and into the game after the end credits but you wont get the choice (its the red option I was tired and chose the wrong one for my tastes, lol)

These are already converted PC files ready to go I've done all the work for you...

Ok hope this helps others who like me wanted to jump in with majority of the game done and most things unlocked but not have to have some NG+++ version where there's basically nothing left to do and the DLC is already beat.

Enjoy!!
