I just play hacks and as such have no idea how to look at the patch.
I noticed from chapter 1 the level-up screen will always "load" at once instead of one stat at a time, and furthermore stats will sometimes go up, without an arrow. Not to mention ,getting growths far above what the stats show as possible.
In chapter 3, friendly unit sprites will vanish if I move the "controller" over them if not greyed out, but reappear when I move to the side. Finally, in chapter 3 the friendly unit sprites down't appear in the character
I don't know how much of this is due to wrong rom, or just bugs in general.
