During this managed to acquire Client files for jp, ru, and nonsteam us/eu beta files.
I am going to share them here now so they are publicly available.
Japan -

Russian -

US/EU Beta -

_________________________________________________
Also, here is the US/EU non-steam launcher released after launch of the game if needed.

Although, if i remember correctly from all of these only the Beta client files are unprotected by xigncode.
I hope with all my heart that this truly one of a kind game could once again be playable for all in the future.
Thankyou for reading.~
