Final Fantasy II (everything8215's disassembly)

A Fight action rolls 0–100 once per point of the attacker's hit multiplier (adjusted by haste or slow, at least 1) and counts the rolls under its hit %, then rolls once per point of the target's evade multiplier and counts the rolls under its evade %. The evaded rolls are subtracted from the hits, at least 0, and the rest are the hits that deal damage. Blind halves the attacker's hit % and the target's evade %. The check returns no successes when the attacker is a toad or mini, and the disassembly marks as a bug that the evade check reads the attacker's status too. ff2/hits

Each hit that gets through deals attack plus a random 0 to attack, less the target's defense (at least 0), and the hits add up. Each hit also rolls 0–100, and a roll under 5 makes it critical, adding the attack again. ff2/damage

Final Fantasy rolls once per swing against a single hit chance that already has the defender's evade subtracted; Final Fantasy II splits that into two sets of rolls, the attacker's against its hit % and the defender's against its evade %, and subtracts the defender's successes from the attacker's. ff2/hits-changes-ff1
