Patch a dll to bypass crc check.

[Gorzoid]

Hi, I was looking at some threads and it seems people are still just modifying the .dll instead of creating inject-able hacks. But they could not get passed the "This server is using a modified version" error. So I looked into the code for the crc check and I found this was the easiest way to patch any dll.

1. Create a copy of the Assembly-CSharp.dll (this needs to be a clean version) and rename it to Assembly-CSharp.cpy
2. Open the modded Assembly-CSharp.dll with hex editor and find the hex value (for the version I was running it was at 0x10472d)

 55 00 6e 00 74 00 75 00 72 00 6e 00 65 00 64 00 5f 00 44 00 61 00 74 00 61 00 2f 00 4d 00 61 00 6e 00 61 00 67 00 65 00 64 00 2f 00 41 00 73 00 73 00 65 00 6d 00 62 00 6c 00 79 00 2d 00 43 00 53 00 68 00 61 00 72 00 70 00 2e 00 64 00 6c 00 6c

3. replacy the d l l with c p y.

It's for when you get the error "This server is using/running/whatever a modified version" in your modded assembly-csharp or stuff, like, when you mod your unturned to have blablabla available but it gives you this error, this fixes it.

Tip: Go through your tutorial and elaborate on the steps. I guarantee you're going to get a shitload of questions from people and if you completely go through this tutorial then I'm certain that this section will be revived.

Also, on step 3: I think you meant replace cpy with dll.

na I meant as in change the last 3 characters to cpy. But thanks for the tip, I think I will go a tiny bit more detailed, since people may get confused with the cpy. really you just have to change the string by 1 letter, but I may just make a program that does this automatically for everyone so I don't even need to give a tutorial.

Lmao if you want. That'd most likely prevent everyone posting "HOW DO I USE". Some people on here are straight ignorant lol.

sorry, just realised notepad++ hex editor turns all 00 into 20 for some stupid reason. updated it with correct pattern.

The problem is that I downloaded a hack and I don't know why but the hex numbers you showed are not in the modded Assembly-CSharp. I was able to fing those numbers in the original CSharp but not in the modded one. Do you have an idea why?

You can search "dll' instead all those hex, if you find Assembly-CSharp.dll just change it to .cpy~

I cant seem to find the offset 0x10472d in my modded dll, does anyone know what it is because I cant figure out how to find the offset for the crc check

[sirzkie]

how to empty the copy?

[BlackHawk101]

I can't seem to find the offset on the current version. What is the updated offset (if it was updated), and also, what hex editor are you using? Because I'm simply using the notepad++'s hex-editor. Thanks!

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?
