You can get/share cards for Illusion games in several sites.
Once the card is saved in Room Girl, it can no longer be loaded in older games. Room Girl is compatible with cards from the following preview games: AI Girl (AI Syoujyo) and Honey Select 2. With the game closed, copy new cards to these folders and the characters will be available next time you open the game. Women cards are located at UserData\chara\female and men cards at UserData\chara\male.
