yeah i want to know where the save file on Linux is located
Here!:
Linux: \Users\(username)\.config\KADOKAWA\RPGMV\Default\Lust Doll Plus(May need to sudo nautilus if you don't have access to .config)
found it! saves can just be dropped right into there
Not quite! You should save inside the game first so that it creates the slot, then overwrite the created save file with the one you want to use!
but it worked
