In 1993, Sega's Virtua Fighter arcade game broke new ground with fully 3D polygonal graphics, a first for a fighting game.To create the images, Williamson took vintage Virtua Fighter game graphics captured in a Sega Saturn emulator and fed them through an "img2img" mode of the Stable Diffusion image synthesis model, which takes an input image as a prompt, combines it with a written description, and synthesizes an output image.Stable Diffusion doesn't work magically, so it can take some trial and error and a keen eye to figure out prompting to get worthwhile results."I tried this thing called 'negative prompting,' where you tell the AI stuff like 'please don't draw messed-up-looking hands,' which does an excellent job in that now your characters have only six fingers instead of seven."In both cases, we've found that the artists doing these AI makeovers are still fans of the original graphics, and the remakes are all in good fun—not an attempt to replace or overwrite history."
