Ah, ledges. I haven't actually attempted this yet, but I'd put an event right before the ledge on Hero Touch that has a fork condition for the Hero facing down (if you are facing down) then use a move event like Start Jump, Down, End Jump. That should do it.
UnrealPoke > a lot of the resources you will use are custom. I recommend using iDraw 3 for the drawing; it's made specifically for RM2K. I have some face sets I can PM you later, as well as some chipsets. As for story, just make sure it's unique. You may not want the obligatory "new region" and "two hundred more pkmn" that everyone has come to expect. How about, you're a kid who's too poor to buy any pokeballs to catch a pokemon and to embarassed to ask a prof. for one, so he steals one from Ash or somebody. Then you have to train the stolen pkmn, overcome its hate of you, become the best against all odds, and face justice and truth to find out what is right. That is a combination of action (running from authorities, etc) with ethics (in the conclusion).
