My ROM hacks
ROM hacking, what fun.
What better way to get started than my oldest public hack, Pokemon Yellow Zelda Heart HP. This hack modifies the HP bar of Pokemon Yellow to change the bar feature to hearts that decrease in fourths. Like an HP bar, the hearts change colors while decreasing to yellow, then red.
This hack has also been applied to Pokemon Red and Pokemon Blue, links are below if you're interested.

Now, why just Pokemon? Here is a hack of Rockman 2, which features the same HP bar modification.
