One day, I was bored. Really bored. I was fiddling with my FE7 ROM FE4-ising it, and it corrupted into DDOP with me opening the ROM at one point. I groaned like I always do, and I downloaded the non-GBA modules because why not. I fired up the FE1 modules. "Surely there's gonna be an item editor and a character editor..." What I got is an incomplete character editor unable to edit growths. "I knew they'd be incomplete, but this is nothing!" So I busted out my HxD and started bashing my head looking for item data. No dice. What I did find, however, is the growth rates! I had a brainwave that all growths are 10% multiples, so I searched "05-04-03-05" instead of whatever 50-40-30-50 was in hex, and I found Marth's growths!
And the class bases too. Did you know that enemy luck can be set to non-zero?
Anyways, that's besides the point. http://www.mediafire.com/download/kwiirpqr9xzma93/FE1_Nightmare_Modules_%283%29.zip
