when i play smackdown vs raw 2010 in pcsx,while playing it shows
R1 CANCE
HOLD R
i cant find R Button in lilypad...

This isnt a pcsx2 problem. Its not even a problem just a minor miscommunication on smackdowns end. There is no "R" button on the ps2 controller, only R1/R2/R3 Im assuming since its not specified its supposed to be R1.

Edit: Or any of the 3 R buttons will do?

Im heard that some games have the commands set to R, R2 and R3. So, i believe R1 would actually be R. Did you try that?
Cuz PS2 didnt have a "R" button.

@edit I remember now. A lot of PS2 games like Soul Calibur 3 buttons doesnt refer to actual standard ps2 controller buttons, but to arcade game controllers. For example, on SC3, you have K and G, instead of Square and Cross.

Maybe thats the thing

R3 button works for sometime as R button but not always .

Please help.
