they have GTA on ds so im assuming you can get it on wii u, but otherwise, i dont really know. maybe if you can get a playstation emulator, maybe postal?

there's a homebrew port of gta3 and vice city floating around out there in the wild

i suggest you try out the actual ports of GTA III and Vice City here on the wii u, they're pretty cool, and play miles better than the defective edition

I tried to install GTA III from WUP and i get error with black screen
