So i bought a ps2 for $15 at a thrift shop. fixed it so it will run games off the internal hdd with opl. everything works great except for one small detail. i have three controllers (2 Dualshock 2's and 1 Dualshock 1) and whenever i use the Dualshock 2's the rumble doesn't work. but if i use the Dualshock 1 (ancient thing that it is) on the exact same game i get the rumble. one of the Dualshock 2's is transparent and i can see that the rumble feature is totally busted but the other one is perfectly fine and the guy i bought it from said that the rumble worked. anyway it's a minor problem and you don't need to rush to get me a solution. thanks anyway.
