only tested on game version 1.2.1 - 100% save and little fan patch.
Since my old 100% save file is already outdated as hell heres the actual new one, also made a little stupid fan patch with a little hint (if you find it

) that helps with finding the dildo for reiko, gave it an option to save before the dinner with the boss, added a guy to endless mode that lets you buy cards and the 1 missable scene and an element you could maybe miss I think and a teleporter to send you back to the world map.
Also added another thing to the park map.
Back up your data folder before overwriting the maps to be save~
Tried all the things and it didn't break anything but who knows~
