Umaro's Dash, Relics & Unequipping All

Edit: Synchysi is faster than me

The "unequip all" and "unequip those who are not in the party" is done by events:

Code:

CC/3510: 4B    Display dialogue message $06DC, wait for button press
               Unequip some party members?
               ^ Those not now in your party.
               ^ All members.
               ^ Don't do a thing!
CC/3513: B6    Indexed branch based on prior dialogue selection [$CC359D, $CC351E, $CA5EB3]
CC/351D: FE    Return

In both events, you have to make some room by either moving the whole routine where there is more space or inserting a B2 command at the end and put the rest of the code where you jump. The whole point of this is having and extra 8 bytes to put the case where character 0D is checked then unequip. I suggest you get the event dump (document where I got the events code) and the event command list. If necessary, compare with the code in the hex editor to understand how a check is made for another character.

As for the other unequip events, you can find them by make a search for "remove all equipment" in the event dump.
