Hi!

I did and all works, thanks! But i created my moded_P.pak for Medieval Dynasty game, but i can't load the .pak in the game.

Game: Medieval Dynasty - https://store.steampowered.com/app/1129 ... l_Dynasty/

UE VErsion: 4.27.2.0

AES key: 0x14D82724CCE5FE6F1899CEA58C14527ACDE5782007136EA9C5135275BFE4A304

Medieval_Dynasty-Win64-Shipping.exe: https://filetransfer.io/data-package/iCiWGBUy#link

1- [EXTREMELY IMPORTANT, PLEASE HELP :D] Can u tell me how I do a sig bypass to load my moded .pak file to the game, please?

And another problem i tried get AES from one game. AES finder tells me the game is encrypted But Steamless tells the game is not DRM. So how deal on this situations, please?

thanks!!!!

Signatures are read at a per-pak bases. What you could try todo is copy the original pak files sig file. And rename it too your Mod pak name and have it in the dame directory as your Modded pak file.

.\YourModLoadingDirectory
   \YourModName.pak
   \YourModName.sig

I know there is a few other ways. But you also should keep in mind that you might also need to encrypt it with the aes key itself.

This is not professional ue4 modding advice, and should work, unless the game you're modding has a drm check and/or way for detecting if a mod is loaded.
