It wouldn't necessary just be the ydr files,
Firstly Molo is a scam artist himself he pays people for their work to and offers them money to put the work on his tebex page without giving credit to the other devs and modders. The work her first released was actually buy a guy who released them on kitbash3d and another modeler ported them to fivem.
so it depends on what modeler actually created it, A bypass will not give you access at all to any of the files only to place them on a server and use them.
Decryption can be partial or full decryption. The guy I know does full decryptions if available but sometimes it will not or at time cannot be fully unlocked.
And I know at this time there is no Molo MRPD thats been decrypted, the Rowpunk MRPD that's been leaked around is actually from Molo himself who leaked it after he updated his tebex page because he was a shit modeler and the map is buggy AF.
