When I accidentally opened my FireRed ROM, it immediately imported it into Delta, replacing the name and artwork with the defaults without asking me if I want it replaced. Luckily, it did not delete my save data. However, Delta should ask me whether I want to replace a ROM if it already exists so I don't have to go through the trouble of replacing the name and artwork if I open it again by accident.
