how to change existing save to work for harem ending?
i changed difficulty variable to Hard using urm but i do not see harem option.
If you are using URM then in this screen during the cycle when Ifuma is talking and appear a path detected (or in a save before or on the choice to enter the cycle)
search the variables "difficulty" , "qi" and "hardend" and remember all those 5 variables and change the values to "Hard" , "600" or higher , and "yes" on the 3 hardend variables you get on the search, I'll attach a screenshot with how I had them and when I changed them. I'm assuming you ended all the girl stories and they are available in the ending screen too.
Alternatively you can chose any ending on this path detected screen during the ending (after the prologue of the epilogue lol that is the same for every ending) just chose the harem ending but probably you need the "hardend" variables later to yes anyway so you get all the content I'll guess, no idea.
Edit: I guess you need the variable end_lover_choice set to "harem" anyway because probably this condition is needed forward too, not sure because playing right now and didn't check any of the very few path detected that appear during the harem ending since I have all the variable set right anyway with the KoGa mod.
I didn't use this tricks anyway because I'm using KoGa mod (that its somewhere in the previous post pages but no idea why I couldn't find it for you, tired already of scrolling thru the posts lmao) that enables the condition for the harem everyone ending, just have to load a save before entering the cycle and appears a screen to change the conditions.
