Okay, recently, I tried pasting some enemies on a screen on a dungeon DMap, and I selected the enter from sides pattern. I tried this in both 2.10 and 2.50. In 2.10, this trick only works if there is an open door on the top or the bottom. In 2.50, this simply does NOT work, no matter which of the two enter from sides patterns I choose. Yet, in any quests made in 2.10 or lower that have enemies enter from sides on dungeon DMaps, they still seem to appear on the screen in 2.50. The only two quests I know of that have enemies enter from sides on a dungeon DMap are Armageddon Quest and Armageddon Quest Forever, which were made in 1.92B1.83. In this case, it is teleporting Wizzrobes that are set to enter from the sides. In Armageddon Quest Forever, however, there does not appear to be a door on the top or the bottom on that one screen, and yet the Wizzrobes still appear. So I'm thinking the quest designer might have used layering on the top or bottom walls.
