The iPhone version of Final Fight was released in 2011. It is a very accurate port of the arcade game, but now features touch-screen controls. The bottom left of the screen features an image of a joystick you use to move your character around, and three buttons on the bottom right of the screen are used for attacking, jumping and special attacks.

This version still has a two player mode, and some extra options in the "special items" menu which allows for things such as more lives. Personally, I can't stand touch screen controls, but if you're ok with them then this version of the game is worth checking out.
