Emulator talk has generally been frowned upon here in the past.
In any case, aside from a recently acquired Wii the most modern console I've ever had is the SNES, so there won't really be anything you can suggest me on that front.
Looking at the suggestions, I've already played House of the Dead in the late 90s (demo on my pc, full game on a friend's Saturn). Completed Operation Wolf/Thunderbolt on the Amstrad CPC... I'm looking for something a bit more modern really.
Come to think of it, I'm suprised someone hasn't made a Flash rail shooter, it's the kind of game which would be well suited to it I would have thought...
