This patch will add a health system based on the "numerical HP bar". However its has been heavily edited and added new features by GreenHammerBro:
-Custom blocks to damage, heal, and increase max HP.
-16-bit HP and max HP, you can now have up to 65535HP, Good for hacks that have made collectibles HP upgrades items that are being saved or RPG-styled hacks. Of course, you can change that to 8-bit for HP being less than or equal to 255 to save memory.
-display HP also as a bar in percentage (based on the HP meter for sprites in the patch section).
-display HP on overworld border, so the player know how much HP they have without the need to be in a level.
-All kinds of sprites (normal, custom, cluster, and extended) now have customizable damage, no more several sprites dealing 1HP of damage.
-perfect knockback, when hit, rather than the need to have higher backward speed, Mario loses control until he's back on the ground. Also, its programmed to knock away from the sprite rather than backwards.
Read the readme and VersionHistory.txt for more info.
Note that the bob-omb explosion itself share the damage as the bob-omb, since the explosion is actually the bob-omb sprite.
-Super status bar patch (recommended, should work with any status bar patches)
-GPS (if using blocks)
-Overworld Border plus (if your hack uses the overworld border)
