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.
