> Your absolutely right! 3 years after its release it can go into mame.
Let me just correct this: the MAME rule is 3 years after something *stops* being sold.
And xiaou2 is shooting at the wrong target: any arcade game that earns at all these days is immediately slapped onto consoles, often while they're still selling the cabinets. And usually the console version is superior for all the reasons I enumerated elsewhere on this thread: XBL/PSN online, achievements, etc, etc.
