As we all know, it IS possible to play Vice City using a controller, although optimizing it was an issue. PS2 controllers work and SOME Xbox 360 controllers work too. This modification it built for most PS3 controllers.
How to install
Drag and drop the given gta_vc.set file into your VC user files. Then launch the game with your PS3 controller plugged in.
Extra stuff
Let me know if there is any bugs. I'll try to fix any bugs that are in this modification. Made on 3/15/13. Enjoy!
