How to create a fully isolated full conversion

[OriginalUsername]

Okay, I did everything EXACTLY like you said (except naming it test_mod, I named it MG. I hope that's not the problem) And I still get an error when I try to start my game. Could I send you my file so you can check what the problem is?

Make sure the path is
redist/MG/
Maybe that what you did wrong?

I bought it on steam, so that should be steam/steamapps, etc. etc.
And what path? I added so many /MG/anything I don't know where
