So I basically have everything ready.
I've got the library, the Meta Injector port, the custom version of resorepless from BlackFireBR (with a small issue that currently appears to be a non-issue, at least with my configuration, I left him a message so he'd look into it) and another project that would make file recheck "dodging" a whole lot easier.
Now I see that the prediction was true, the "anti-modding" update made it to more regions. I don't have access to any version besides the NA version, so I'm going to hold back until after the NA maintenance, to see whether the same patch made it through, and see if there are any other usable workarounds besides the library, that is because once I release the library, there's no going back, and while I am confident there isn't much PA would be able to do to stop the library, it would still put a bigger target on our back since it would enable things that PA made efforts to prevent before (anyone with a slight bit of intelligence here knows exactly what I'm talking about) and so much more.
