This is a simple hack with the nightmare. Here is some details you should know.
It'll have everybody start promoted including enemies.
The difficulty is increased(hopefully not to much),
weapons are increased,
pre-promotes are useful,
And no one I repeat no one is almighty(except the girls who are very powerful).
Expect very strong and hard final bosses.
Cap level reaches 30.
Promotion items are weapons.
Promotion parade for FE 6, 7 and 8.
Classes stats cap increase.
Ultimate weapons have many clones.
Halberdier animation(maybe)
Enemies start promoting for the games;
FE6: After you get Lillina.
FE7: The chapter you get Wallace.
FE8: Ch.5 or at the beginning.
If you don't like supports then don't play this game.
That's all for now, I'll keep on adding as I remember.
This is where I put the link for the patches;
fe6 up to ch 8x http://www.filefactory.com/file/b07b4e9/n/...tion_parade.ups
