well i imported the japan version of dual shock and its working fine with game like DMC 4 but the dual sock doesnt rumble in games like heavenly sword and resistance...how it can be sloved

i dont think all games are compatible as they where made long before dual shocks release though they may bring out patches

All games released in the future will have a special Dualshock 3 logo on the front if they are compatible with the DS3. So. look out for that when buying games in the future so it'll save any more confusion...

Keep reading down...

No dont worry i have the solution.

Is your PS3 connected online? Resistance and Heavenly Sword both need a Patch to enable the rumble feature. This patch will automatically download if your PS3 is connected online.
So if your PS3 isnt connected online then this is why it isnt working....

Heres a list of all the titles compatible with the DS3:

Need a Patch first:

Formula One Championship Edition
MotorStorm
Resistance
Go!Sports Ski
Folklore
Heavenly Sword
Warhawk
Super Stardust HD
Blast Factor
Rainbow Six Vegas 2

Do NOT need a Patch:

Gran Turismo 5 Prologue
PAIN
High Velocity Bowling
MLB 08: The Show
Uncharted: Drake’s Fortune
Ratchet and Clank:TOD
Snakeball
Toy Home
PSOne Emulation games
Piyotama
PixelJunk Monsters
Condemned 2
Lost
Burnout Paradise
Dynasty Warriors 6
Devil May Cry 4
Dragon Ball Z Burst Limit
Turok
TimeShift

And as i said games that are compatible in the future will have a DS3 logo on the box.
Hope you get everything working...
