How difficult would this be? NEW GAME +

Gi - Event bit $066 is not unused. Are you sure it isn't $061?

Ah yes, you're right, event bit 66 is totally used. I meant the event command:
66 : 5    : Nonexistant. Unused in standard game.

I was also incorrect in saying that the event code bytes are "few", I forgot that there is a bit more general event coding in regards to handling the characters, 168 bytes or so... but that's not much still considering it does leave out all that bit clearing.

Makes sense. Joshua, note that if you're going to put this code into Divergent Paths, you will run into a conflict. I use the following new event commands:
66 - Check a character's equipment (used when recruiting Kappa and for Vargas's command switching)
67 - Teach a magic spell to a character (used for Paladin Banon)
A3 - Change a character's command (used for Gau learning Fight and for Vargas's command switching)

So if you use the NG+ patch, you'll want to move it to event command 68 or 69.
