I played around with hyperspin on my non-dedicated machine (intel i3) and thought it was complicated. On my mame cab pc I am using gameex, its really easy to setup, nulldc works just fine straight from the front end with no mouse input at all. I like hyperspin, but am not sure that I want to go through the hassle of setting it up when gameex is just so much easier, plus I am not sure if my system is beefy enough to take advantage of all the bells and whistles (P4 3.0ghz, 1.5 gb ram, ati 9800 video card)
