This lora was trained on 302 pixel art images of The King of Fighters sprites of characters on victory portrait screen (Neogeo/MVS).
Results tend to has 6x6pixels since all dataset was upscaled to that factor, so you might be able to do pixel-perfect with the generated image by normalize it to a grid 6 times smaller.
(I fell the Flux version is undercooked since it had only 8 epoches because it take a lot longer to train. What I mean is, it doesn't have that ressamblance to SNK pixel art, but it performs well)
