Here, my video of some examples of ASM hacking of Zelda II: Adventure of Link
Zelda II ASM HackingThis video shows many examples of ASM hacking on the NES game Zelda II: The Adventure of Link. All enemies were altered in some ways. Some modifications are simple variable tweaks, while others involve ASM code created from scratch and incorporated into the original code... Enemies move faster, attack more often, projectiles have greater velocity, many aspects of enemy routines are more randomized...
Comments and suggestions are welcome...
