During battle startup, the game loads each item a character has equipped to handle stats, status, etc. For a given character and equipment slot, function C2/0F9A loads the corresponding item in memory. In case of a weapon slot, if the other slot is empty or holds a weapon, it will designate the other slot as the attacking slot. That is not what we want so we assume that the other slot is not empty and does not hold a weapon.
In function C1/9D95, weapon graphics and sound are loaded, with A being the weapon id + 1:
C1/9D95: 8D6A62 STA $626A (A contains the weapon id + 1)
C1/9D98: C220 REP #$20
