I got it!
But I still don't understand one thing.
If NES Dungeon Screens normally can not trigger (Block->Shutters) Doors of other Dungeon Screens,
what is the "No Reset Doors" (Up, Down, Left, Right) function, in the screen state carry over used for?
...'cause NES Door mechanic is actually working in NES Dungeon Screens, only.
Maybe this Question sounds stupid, but I have really no idea.
Thanks for helping me!!!
BTW, I still need help in many other ways.
The more I learn, the more questions I have.
