Dividead - Savegame editor
Another one of the early savegame editors. It basically consists of a levelskipper, endforcer and a CGCheat, it is quite an asset on this game though. You have to fiddle around a while if you want to complete the game with all endings without it :)

Maids story - Savegame editor
One of the newer editors, controls pretty much every aspect of the game, girls affection, date, money, inventory, furniture/accessories and everything else exept 'night training' if I removed this it wouldnt be much left of the game would it?
