http://hosted.filefront.com/ze88roI've uploaded SceneReader and Scenester onto my FileFront account because I forget where I downloaded them from originally, and I am too lazy to dig up the original links (these are, of course, not my work at all).
The first program, SceneReader, will allow you to extract the game's scenes from your scene.bin file (/data/battle) and Scenester will allow you to edit the scenes. There's also another program out there, SceneEdit (made by the same dude that made SceneReader), that works like Scenester, but I don't recommend using that one because it's sort of buggy. I haven't encountered any problems with Scenester personally, but then again, I haven't extensively tested my experiments.
The usage of the programs is pretty self-explanatory.
But I wanted to add a little personal note that I think you guys may have touched upon slightly...super stats do not a difficult game make. Making the enemies use more clever/powerful spells, or attacks, or status ailments, is what really makes the game more difficult. I mean, additional strength and hit points wouldn't hurt, but doubling those stats just makes battles last twice as long and makes them twice as tedious...not necessarily hard. You could just level up more than you usually would, which is
never fun. The fun part comes from determining an enemy's strategy and exploiting it. Or at least that's how I feel.
