not minding the title here..
if this is all so easy, wouldn't we have seen Street Fighter IV all over the net months before its console release? it's X2. and if any title were to push people to crack some security, that is it.
besides issues of encryption, i think there's just too many games now, with relatively very few in the arcades. anything that comes out in an arcade on something like the X2 is just going to be ported to the home systems in a matter of months with more features, possibly better graphics, and internet play (eg. SF4!). pirating this arcade stuff, for home use anyway, just doesn't seem worth the hassle at all.
