I mean linking vibrations to values(memory adresses) like in cheat
search and cheats. Everytime value rises or lowers or just chenges,
pads or joystics or other stuff with vibrator inside could vibrate.
List of those could be stored in file(like cheats).
Example:
I play Secret of Mana.
I link this efect to main characters hp.
I selsct option lower, and my pad vibrates when hp lowers.
So when I(character in game) got hit, my pad vibrates.

This is only my idea but i hope zsnes team could add vibration
efect to zsnes( and I hope it is understable what I have written here

P.S. I know my english is very bad, so ask if you don't understand
something.
