So I'm playing hard mode and I decide I just can't wait to be able to pierce enemies so I can shoot some damn bullet bills out of my way without wasting ammo or using the horribly slow weapon with megaman. The best way I thought of to get this cheat over with is to trap a turtle shell between a pipe and a cannon and just let it go on. I've noticed that I'll always get the cheat if I am stomping on the bullets manually. But with the 'shortcut,' you'll be amassing extra lives with every bullet (after 7). And the cheat will never activate. The number of armored enemies killed will pass 200 and nothing happens.
