I'm playing Awakening right now and have encountered the same frustrations I felt in previous games.  What are the differences between normal and hard mode?  Is it just more reinforcements, or are enemies leveled up higher?  Also is there some sort of hack, for any of the FE roms, to get rid of reinforcements?

Also is there a way to hack any of the game roms to be able to progress past level 20?  And speaking of leveling up if I choose to use the master seal on a level 20 character, instead of lets say a level 8 character, will the amount my stats increase be the same?  I'm just trying to see if waiting later to use the master seal will allow me to maximize character stats later on in the game.

PS:  The level 20 limit, particularly on hard mode, is such an AWFUL concept.  I don't understand the point at all.  If I want to focus on making a few characters really powerful why shouldn't I be able to do so.
