I want to edit the compiled DLL code to bypass the variable checking condition. I tried to change the value in the condition but it causes an application crash. How can I "remove" this condition?

Here is the condition (if statement) enter image description here

And here is ASM code enter image description here

I was trying change the HEX from 83 F8 FF to 83 F8 01 but application crashes.

I don't want crack anything, i want remove version checked because library is older than actual game version

  • and after the change, is everything looks ok in the disassembly? It might be that there are some checks that detects modifications and crash the game Mar 20, 2021 at 19:16
  • It may not be that easy. Possibly the data initialised is used later on, in sub_180005AD0 for example, and since it doesn't contain what the program expects, it crashes. Try to debug the patched version: put a breakpoint at 1800060EA and keep pressing F8 (step over) until it crashes. You will find the procedure causing error.
