This is an experimental take, at a way to emulate the 'five screens away' model, of making enemies return. In undertaking some code to force splitting enemies not to always return, but also not to never return, it struck me that there was no easy way to recall them, (from forced removal) without a way to mimic this engine behaviour.
The following, is an experimental method of simulating that behaviour. I look forward to any thoughts, insights, or suggestions...
//Five screens away
//v0.2.1
//For RPG.zh v0.97.5
//Sets a screen register, if Link is more than five screens away, on all screens for a given DMAP.
