Values for Rockman 2 Boss Weaknesses – Document

1 – 14 =  Mega Buster

15 – 28 =  Atomic Fire

29 – 42 =  Air Shooter

43 – 56 =  Leaf Shield

57 – 70 =  Bubble Lead

71 – 84 =  Quick Boomerang

85 – 98 =  Crash Bomb

99 – 112 =  Metal Blade

Written using Google Sheets, this is a list of code addresses for the weakness chain of Rockman 2. With this document, anyone can create new weaknesses in the Japanese version of the game. I decided to write this after noticing that it was never included in Mega Man 2’s ROM map page on DataCrystal (link down below). The numbered legend above pertains to what boss is affected by a certain weapon. According to Overseer190 on DataCrystal, the Japanese values for Mega Man 2’s weakness chain are located further up in the ROM, beginning with the address 0x02E933. Also included in the zip is a hexadecimal chart to help romhackers with configuring new values. For starters, the hexadecimal version of the number 10 would be 0A, which is how much damage Crash Man takes from Air Shooter.

P.s, Time Stopper is not included in the weakness chain because it was not listed as part of it in the ROM map.
