Idk what to do all games look fine except the 2 super mario world cartridges mario looks weird
Hello, I believe the part of your cartridge which contains Mario sprites is broken, and as far as I know it cannot be fixed, the only thing that I can suggest is to take apart the cartridges and clean it but I really doubt that this will work.
It may be a problem with the PPUs. Check for broken traces around them.
