Converting a FiveM YMAP to single-player?

[5SL0]

So far I have tried about three different ways of structuring the files, all as a "dlcpack" folder, but to no avail. I've tried looking specifically at the Mission Row PD and comparing the FiveM version to the single-player version, but I just can't figure it out. I have sent that author a message, but there's no guarantee he'll even read the message, much less respond (he doesn't owe me, you know?).

Thanks in advance for any help!
