I used to have the playstation version, I remember I couldn't figure out to make a shop or do a lot of the other stuff until I accidently stumbled on the second page of event commands. I don't remember much about the program, but I do remember in order to move an event you had to switch to that event first. So you'll have to have an event that the character steps on then it switches to the event of the person who walks up to the player.
