Built-in HRP is initialized after LoadOriginalDll(), HRP::Setting::ExternalEnabled() will always return 0 when called in the function. IMO people who want to use an external wrapper should take care of those settings themselves. Also, it's preferable you actually compile and test your code edits instead of simply using GitHub's web text edit function.

Tell me how to do FileExist for f2_res.ini in your project and I may find a solution to all problems

I could have compiled the build locally, but it looks like my provider's DPI has gone crazy

@NovaRain I collected all the changes into two commits, compiled them, and tested them.
