The Skirty cheat is a registry edit that, in Creatures version 1.0.2 and above, different from the Doctor cheat purely because it opens world.sfc by default. The Skirty cheat allows the user to switch worlds, pick up creatures and scroll all around Albia. In Doctor mode, Creatures does NOT autosave. Use with caution, with either Gordnorn and Rhodent's BoBCoB tool or Alexander Laemmle's BORG utility. This cheat mode is a successor to the Darwin cheat for Creatures versions 1.0.0 and 1.0.1.
