I only play on my cabs, but using my right hand to bash buttons a la R-Type just isn't on anymore, which is a shame as I just bought a genuine Irem R-type PCB a couple of weeks ago.
I now use my left hand for using mice on my PC as RTS games from the past with all their clicking buggered it up even further. I think I was trying to find a pedal controller so I didn't have to click so much, but couldn't be bothered in the end.
I'll see if anything evil controllers can help, so thanks for the heads up.
