I guess that sometimes I have that problem... When encoding large roms, it hangs for a bit... Just leave it and let it run, is my guess.
And uh... honda, Children of Mana is cool and all, but don't you get bored of the dungeons?
Even though you get different tasks to do, it's essentially the same dungeon (w/ random layouts of stages) over and over, with only the discovery part being somewhat different :S
