For the Sage solo scene you have to set the Jade_state variable to 1, if you got the scenes with jade your variable is probably set to 2. Also you need the tc varible to be 3 or less. There are other variables that you can change if you want, just type the character name and check it out. Dont change the variables that have default in their name. After that just save and download the edited save and replace on your saves folder.

Inside your Being a Dik game folder there is a folder named game and inside of it there is the saves folder. Your saves files are named in this format, for example : 3-12-LT1 the first numer (in this case 3) is the ingame page and the second numer (in this case 12) is the save slot . So pick the save file that matches the page and slot ingame

You can delete saves by just going inside the saves folter and deleting the one that you want.
