It's exactly as the title says. I wanna rewrite the coding for one of the bricks to make it hurt Mario, but I have no idea where to start. I already know enough ASM to pull off something like that, since I inserted objects all the time in my SMW hacking endeavors, but that game had assemblers that would insert the coding for you, where as this game... doesn't.
Was I clear in what I wanted to ask? I think I might've rambled, but I want to make sure I don't get a "lern azm" reply
