This is a MegaMan/Rockman patcher/randomizer to modify the major boss-related RNG. This could be used to make for better head-to-head races. The mod specifically allows customization/removal of the following:

• Drill man: drill events, including the initial one
• Dust man: suck events
• Skull man: skull shield delay
• Square machine: 1/2/3-pass
• Met Man: open/close durations
• Tako Trash: Fireball/bomb attack
• Dr. Wily: Spawn location customization (by row); duration of hitbox and respawn delay

You can fully customize to your liking or generate randomized/blind ROMs:

The readme has the code and brief descriptions of the RNG for those interested. The title screen has been modified (replaced ‘WORD’) to show the patch/version.

The included patch gives the easiest options possible for all bosses. Please note MegaMan and Rockman require unique patches due to slight differences.
