As already said many times the controlls work fine, but the Feeling is different I guess. I am playing Virtua Cop now by myself. Have to play it with the Controller though because I am still in the process of Looking for a decent CRT monitor and a lightgun.
On my LCD with the Framemeister and I can only play with the Standard Saturn Controller. It is not unplayable but the game is quite hard with just the Controller.
I am still having fun with the game. Good atmosphere and Soundtrack and I also like the love for Details. A really nice touch that you do not have to kill your enemies to win. You can also just wound them.
