But... what does coding have to do with a map editor, unless there is a function I never used, the coding is up to the script editor you use.What I've always had trouble with is the coding. You should make this as simple as possible for those who are beginners at coding and don't know anything about it.
I still can't believe I haven't fixed that yet. XD
But this is normal, I haven't actually added that yet.
Also, I've added Day/Night pokemon support to MEH, so you can add different Pokemon to different times of day. Currently it requires primaldialga's DNS although a different system may or may not be released at a later time. Also, the tool currently doesn't auto-inject the ASM, so it's kinda useless for the general public at the moment. But for those who want to try it out, here's the ASM:

These are for Fire Red and replace the two routines in this thread. Insertion is exactly the same and only those two routines are required. It also supports swarming although it's disabled by default, but can be activated using the flag at the bottom called "enable_swarming". The how-to on this is also in the thread, although the variable for the map operates slightly different. To change the map, set the variable 0x4FFE with the top byte as the bank and the bottom one as the map. So if I wanted a swarm on Route 1 I'd set variable 0x4FFE to 0x0313, since it's bank 3 and map 0x13 (19 in decimal).
Well, I'm happy to say that unlike Amap 1.92, when I save the rom after editing it with this, I can still open it in GBAPGE, though I can't delete events so I can't test that portion.
