Why this works: The act of "Running away" while holding a direction resets the volatile RAM state for the encounter table. When you re-enter the fight, the RNG is stuck on a specific loop. By killing the enemy immediately on the first turn of the new battle, you freeze the RNG on a "high drop" frame.
Your party’s cumulative Luck stat influences drop rates, but not as much as rumored. Testing shows each point of Luck above 50 adds ~0.1% to drop rate. So a 255 Luck character (max) gives ~20% increase—still not 100%. suikoden 2 drop rate cheat
To cheat: Use a GameShark code to set all characters’ Luck to 255: Escape from the battle
