Many thanks to chieftex and saber_breaker88 on reddit for the post here. This gist just adds some more notes and updates to those instructions, this was followed successfully on 2021-09-03, some steps have been removed (e.g. with flatseal) since they were not needed at that point.
The instructions below seem quite long, but they don't actually take that long to run - about half the time is just getting CEP set up on Windows so we can copy the files over, the whole thing should be doable in half an hour to an hour.
- On Windows, install P4G and go through the whole process of applying the mods you want, following instructions on p4g.cep.one. When this is complete, you should be able to run Persona with the mods successfully.
