Looking at games of the era there was a clear divide between ones that tried to effectively render a photo on a NES and ones that stylised the image in a more anime-like way.

As such, I've added some simplified and more cartoonish versions of the profile images. Nothing super-drastic, just cleaning up a lot of the non-essential detail in the artwork.

These don't replace the originals, so you now have a choice between either style.
