Whenever I try to import a custom sprite, it just turns into a Shelless Koopa when the game begins! As an example, the one I want to use the most is a P-switch
at but the same thing happens! The Sleeping Galoomba
turns red. I've tried everything, from setting the extra bit on or off, to... um... what else is there to try? I edited the ASM on the P-switch a little bit by just swapping the
palettes. The code itself is not edited or faulty otherwise.
