** What this literally is is how far into the object handling chart in memory ($0420 - $043F) the projectile generation loop is going. Weapons are normally stored in $0422 - $0429, so with a maximum of 3 bullets on screen, the loop checks $0424, $0423, and $0422.

  • 0x03D4A7 = Velocity of Mega Man's buster shots (Default: 04) [NOTE: Shots that are too fast will not be able to properly register hits at all, so avoid going beyond around 0B.]

    • What this literally is is how far into the object handling chart in memory ($0420 - $043F) the projectile generation loop is going. Weapons are normally stored in $0422 - $0429, so with a maximum of 3 bullets on screen, the loop checks $0424, $0423, and $0422. Increasing this past 0F enters the enemy handling range ($0430~$043F)
