oh hello copy protection, fancy meeting you here
oh hey that's fun. this game has two layers of copy protection! if I hack the "check weird sector" code to always return 0 (for found-it), it tells me "Diskette/version out of phase"
they call the copy protection on two different sectors, and throw the out-of-phase error if they give the same result, I think
so you can't just overwrite check_copyprotection_sector with return 0
