Mmmm, I played one in Belgium a couple of times. For me it misses SI's biggest attraction: the half-mirror set-up with the moon lit by black light etc.
Expect to play SI like you would on MAME, black background.
Qix is an "acquired taste" game. Some love it some hate it. I played it pretty often on my A8 BITD but the arcade version is a LOT harder.
