 	Alternative patterns exist so that the patches work on older and other versions (there are differences between Chromium 80 & 81 and Chrome & Edge (do they use another compiler?)).
 	Patterns here are stored in the default IDA format. ? is replaced to 0xFF in the C# code (and is still treated as a wildcard).
 
-	Normally, I prefer JSON over XML, but C# already has XML parsing built-in, so no extra library is needed.
-
 	Create a new issue if a pattern stops working with any browser.
 
 	New method: Debug Chrome in WinDBG, download the respective chrome.dll.pdb and load it for the chrome.dll module (lm -> ld ModuleName /f FileName) (.reload may be required). Then use x /D /f chrome**!*FUNCTION_NAME* to search for functions. Note down the offset and find it in a disassembler to make a pattern/signature.
