07 uses a texture without mipmaps to display the jerseys so they are very sharp and detailed in 512x512. 06 uses a texture with 3 mipmaps instead so the jerseys gets very blurry.
I don't know if someone allready noticed this.

I've hexedited the jerseys fsh files so the jerseytexture is used without mipmaps.
That means the game allways uses the 512x512 jersey texture and there are no blurry jerseys ingame or while zooming out in replay anymore.
