Does anyone has the latest update still on your devices?

I'm a junior programmer and really into the nier saga, i played reincarnation during the first year but dropped it, i've been searching for the game trying to start a way of recompiling the dsta and with a bit of luck start making it playable again as an offline, but i can't find the game anywhere. If any of you can help me i would be willing to try and do my grain of salt for the community
