Apparently the new update is out on ryuugames.
Started playing it again after the update and it there is a samurai looking dude in the main big town which initiates the new content,you need to go to the hidden elf village to continue
also the unlock memories crystal does not seem to unlock the newer stuff so there is that
EDIT:I finished the new dungeon (have to do it 3-4 times) and the arena thing so i guess thats it in terms of gameplay content,missing the Lose screen from the new endboss and a bunch of scenes from the second category in the recollection room despite having allready seen them so i guess it might be a bug
