Oh I forgot to mention that in order to install the english patch, you have to unpack the the files via the built in mod tools. I will write instructions when I'm free later. Pretty easy.
The english text is slightly bugged due to using an older version of SDLPAL but can be fixed by downloading the nightly build of it via SDLPAL's cloudsmith page (linked at the top of the readme on GitHub).
