Hi! Before you say, "Why ask? The Rumble Pak is utterly useless," I would like to note that DeSmuME supports controller rumble whenever you have the Rumble Pak selected for Slot-2 and the game commands the DS Rumble Pak to rumble. And some flashcarts support it, too. So, that brings up a few questions from me...
1. How exactly does this work internally, and how can I replicate it whenever a certain sound effect is played (for example, the engine of a car)?
2. Does the Rumble Pak have different of rumble strength? If so, how do I program that?
Please keep in mind that I am relatively new to ROM Hacking. So, if you could kindly point me in the correct direction, that would be splendid.
