This patch is the other half of the 'Imp's Map' patch that changes characters who have Imp/Pig status to the Pig sprite for the area maps as well as the overworld. It was broken up as an optional patch because for the area maps there's a palette issue that still needs figuring out, and because it can potentially take away from the sincerity of events.

All credit for the original patch, Imp's Map, goes to C-Dude and Serity.
