If you're talking about the "Global." and "Config." files in the save file, don't worry, you can play with this save without changing your files. All you need is for my save, the one I sent you, to overwrite your save. So if you don't already have a "file1.rmmzsave" save in your folder, simply open the game and make a save on slot 1. A file will be created which you can then overwrite without any problem.
Here's the full save folder anyway, if you prefer to try it like this !

You want to have more lust? If it's just that, talk to the man with purple hair under the tree in roselake's park, he will give you +2 lust. Then the blond merchant in roselake's market, at the bottom left, and then the man with a mask sitted in front of the tavern. You'll then have enough lust for the rest of the game
