Custom sprite tileset change

Hi everyone!
My question is about bro sprites on this site, namely these:

I'd love to use these sprites in my hack, but the thing is that they use SP4, but I'd prefer them to use SP3 to overwrite chuck graphics mainly. Is there a way to do that? I don't know much about ASM.

Closing this because said thread is identical to the one in the ASM forums and we want to avoid duplicates. If you wanted to have that one moved, you could have asked a moderator who will evaluate whether that move is necessary (personally, posting it here is fine as it is considering it doesn't really require ASM knowledge beyond editing tables and defines).
