Who’s reverse-engineering game data files for fun again? That’s right, it’s me. I decided to go digging into VVVVVV this time around. Turns out there’s not a whole lot to it. Everything is wrapped up in a file called data.zip, which is just a standard zip file. Spritesheets are just PNGs. Sound effects are wave files. Levels are XML documents which have been given a .vvv extension for some reason.
