Patch a dll to bypass crc check.

[hugerichman]

The patcher does still work. As I have just tested it.

Btw, what would I need to learn to start creating dlls to inject?

I just realized it still does work. I just wanted to learn how he found out the offsets, thats all.
And if you want to get into creating dlls, learn C++.
Also, watch some youtube videos, I recommend GuidedHacking.

Alright, Thanks for the guide!

The answer CyberAce was more generalised towards normal dlls. If you want to start creating dlls for Unturned you will probably want to learn .Net (mainly C#). Hacking C# games with C++ is a excessive. Once you get a basic grasp of C# go look at the tools used for creating and injecting c# dlls into Unturned (or all Unity games).

Oh and if you were talking about making Assembly-CSharp.dll's then you can check out the stickies on this forum, there is one tutorial there about it, it is a bit outdated but really its just that there paths are different and you will need to patch the crc.

How were you able to find the offset where the version is located? CE?
Now that the game has been updated, your auto patcher doesn't work and I need to manually find the offset and replace the bytes. How do I do it?

I made a comment on a thread about me trying to find it, i will find it and repost it here,

the error is coming from private static void SDG.Unturned.receiveClient(CSteamID steamID, byte[] packet, int offset, int size, int channel) the server sends an ESteamRejection in the packet and then it brings you back to the menu with that error. the server also handles it in the same .cs private static void receiveServer(CSteamID steamID, byte[] packet, int offset, int size, int channel). I'm not too knowledgeable with hash checks but hopefully this helps, just search for WRONG_HASH and you will find it

---Update---

here is some data I found

byte[20] objects[4-6] are hashes

hash_0_1(4) = hash of server password -- not gonna be this there is no password
hash_0_2(5) = Level.dat file in Maps -- we are not changing map so not this one
h(6) = one of 7 hashes in appout.log sent in byte objects[7] which is always 1 so its the second hash (20 bytes, so from 0x16 to 0x29) -- hash of the assembly csharp.dll. found it!

so, to bypass you will need to either change in Provider.onLevelLoaded where it sends the hash using Provider.send, or change ReadWrite.appOut where it creates the hash in the first place

Just made a post on it https://www.mpgh.net/forum/showthread.php?t=1068320 its pretty fucking simple.
