You did the popful mail world map! I found that on line years ago but did not know who it was from. sorry about that I'll ask JonLeung to give you credit for it then, OK.
I'll try again with BGMapper on Lady Stalker world map. Popful mail cave stage has this circle around mail and every thing out of the circle is dark. any way of getting around that. I mean is there a way to illuminate the whole screen? As for a Lady Stalker walk through walls
cheat code, I'll ask my bro for help, see if he can figure it out. I hope those two games get translated some day. Would fully mapping them inspire anyone to do that?
As for dark half and energy breaker your right about that the main difficulty would be the arranging the rooms. Most of my time in landstaslker and other large games was connecting the areas together. You want to make it easy to follow but also preserve its look without clustering the map sectors with overlay, lines and labels.
