DJ MAX TECHNIKA (PS Vita)

I don't know that they're completely fine with it, but they know of many sites that host simfiles/emulators and have really done nothing about it. It's really kind of marketing in a way. My friend used to play DDR very rarely, maybe once or twice a year, and when he did, he would just choose the same three songs on basic and get off the machine. I showed him Stepmania and he immediately had me install it on his computer. Now he wants to go to the arcade all the time and play DDR and is more varied in his selection (he seems pretty fond of the X2 license list).
