Thank you i got it working thanks to your explaining !I just checked it, and it works fine. It should work for every version unless additional girls are added with their own variables. For it to work you must go into the folder games > scripts and find the RPY file that says "Setup" then delete it. Next you copy paste the script I modified and change it's name to "Setup" removing the numbers on the end that f95 adds for some reason unclear. Then start a new game. Only works off of a new game.
If you are NOT deleting the other script then renpy may be reading the original setup script instead that has stats all at 0 to start out with. I'm unsure what happens if you put two scripts in the same time one saying have 99 stats and the other saying have 0 stats. I guess one will win if it don't break everything.
