This mod replaces the vending machines of Sprunk and eCola for new ones of Pepsi and Coke. The textures are in 1024x1024, that ensures a better quality than the originals, even on higher resolutions. Maybe it doesn't work in the first missions in the Roman's office, but no game crashes (tested in my own PC). A good place to find them is in the room below the Statue of Hapiness. Don't forget to make a backup of the files!
