I managed to mess up again

the ending is still fucked and that requires some save editing to fix

(or you can play the game again after redownloading , your choice)

to find the saves go to C:\Users\ (YOU) \AppData\Local\Jigoro

edit

ending="1.0000"

back to ending="0.0000" ot whatever, change the 1 to a 0

then overwrite and enter lux to see the ending.
