I must admit I play many of these games emulated and love them. I also have a many original Street fighter games on various platforms. They've had enough of my money to play these games. If you fancy playing these games in great quality you can on android and windows tablets and many other devices but its most important the actual gamepad is fit for purpose and its on a setup with low input lag. Otherwise not only are you paying a lot of money for an old game but its just not the same game experience either.
