Dude, guys, he's not HACKING the game, he's making a hacking tool. Doing weird things like improving the password system is not part of the goal. And anyway, the editor can only interface with Megaman X. Its sequels will require a fresh approach. I wouldn't expect Xeeynamo to work on them anytime soon if he's not even satisfied with the first one.
Also, inputting graphics can be done with a program like TileLayerPro. It's a lot of work, but you don't need a multi-purpose editor to do it. In fact, the editor's functions, so far, don't accommodate that kind of project very well.
