to sx/amiga:
well, my pad was the same one as the dual power, but without force feedback....however, I read many positive reviews about the force feedback version so I got one after all....so yes, now I have two similar pads, one with force feedback and one without.
BUT....
the dual power runs completely on your CPU's power supply...needing no batteries is handy, but in my case it crashed after a while.
why? my computer already has much devices in it and this pad was more than the powersupply (a standard one) could handle....fortunately nothing was broken due to this, just a crash, so I got myself a USB hub the next day, because I didn't want to return the pad now I had experienced the fun of force feedback
So I added the USB hub, had detection errors, installed a truckload of fixed and patches, and hey! it worked! I now even have both pads working so you can imagine that that's pretty cool for 2 players in vgs, epsxe or other (psx) emulators...
I found the force feedback itself to be working very well, depending on the game though....Especially the need for speed series really shine when you use force feedback. I haven't tested epsxe yet, but so far I think the force feedback is pretty strong, about the same as a psx dual shock controller (and perhaps even a bit stronger).
So maybe the weak force feedback with your pad is caused by lack of power (in my case it crashed, in your case the ff might not work correctly?).....or you just need to download the latest driver from
www.thrustmaster.com, that might help.
Oh, one other thing: I found out that the dual power is also slightly improved when compared to the older non-ff version...the button numbers are more logical (1,2,3,4 are on the normal place, with the other pad those are the shoulder buttons, this can cause problems in games that lack button configuration) and the analog controllers are slightly more accurate.
Conclusion: the pad works great here, really solid and stuff, and hopefully my tips will help, but, like the man who sold me the USB hub stated: the fact it runs solely on your computer's power supply is just plain evil.
wow, that was almost a full review
