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

oh god they overwrite the DOS interrupt 1E in the middle, to make DOS think it's a different kind of floppy disk.

okay I now know HOW to crack the game, I just gotta write the x86 assembly.

normal people don't do this. normal people don't write 16bit DOS assembly in 2025.
