Update 20241224
- Patch Dll file recompiled to defuse massive false positive detection of the last days (it's fucking annoying)

First, thank you for this patch! I've been playing with v1 of your patch for years.

That said, I've been having trouble with getting this patch to load successfully in some cases. I think it has something to do with the location, or with some metadata that Windows has attached to the location.

For example, I have a working installation in "C:\Games\COD2". I can tell that the patch is working fine by e.g. enabling WindowedMode or NoStartupBlackscreen. I copy-paste that working folder to "C:\Games\data" and run `CoD2MP_s.exe` from there, I can tell that the patch still loads. If I copy-paste the installation to "C:\Code\COD2\data", it stops working. No matter how many times I clear out that location and copy-paste the working install to it, it does not work. When it does not work, I get the long black screen, and some of my settings get reset. I've tried copy-pasting it to other places, and sometimes it works, sometimes it doesn't.

These installations are 100% identical at the time of launch due to the copy. If I attach to `CoD2MP_s.exe` with the IDA debugger, I can tell that in the cases where the patch gets loaded successfully, the `winmm.dll` in the folder alongside the `exe` gets loaded, but in cases where the patch doesn't load, that local `winmm.dll` never gets loaded. I think it might have something to do with certain threads starting earlier for some reason, but I am not sure.

I am very confused about what might be causing this. I hope you might be able to replicate this issue via copy-pasting your installation. Otherwise, would you consider offering a pre-patched version of `CoD2MP_s.exe` for those of us who run into this issue?

Thanks for the feedback, I will look into it.

Edit:
It works on my end in path "C:\Code\COD2\data" and can't reproduce it.

Try the following:
1.Open the "CoD2MP_s" exe file with e.g hex editor or cff explorer and change  -> "WINMM.dll" to "patch.dll" -> save.
2.Rename winmm.dll to patch.dll file and test if it changes anything

Sounds strange in any case. If anyone reads this and also has the same problem, please contact me.
