you need to use a plugin based emulator with the cyberpad plugin.

 

And the game should support that feature.

 

Have the Plugin NOw!!! But MORE QUESTION!!!!!

I have cyberpad plugin now!!
Cyberpad.dll, isn't it?

Where do I put this dll??

I just want to know what the different between ePSXe and PSX is.
I've both of Them. And THey both can run PS1 games.

And Which is the best if I want to do multiplayer (with LAN)?

 

I dont think pSX can play LAN but I know ePSXe can if you place your Cyperpad into the Plugins folder you can configure it for LAN.

 

epsxe needs a little more configuring then psx
