@dav333 said in Adding older Love engine version:

Is such a thing possible?

Possibly, but I haven't tried installing that particular version of LÖVE, so some adjustments might be needed for installation.

I removed the 0.11.1 and 0.10.2 Love engines, but the result was the same.

I don't think that would solve your issue - or has any influence on the command you're trying to execute. Exit EmulationStation, then run the following commands

mkdir src cd src git clone --depth 1 --branch 0.9.1 https://github.com/love2d/love love-0.9.1

you should now have the sources for the version you're trying to install in the love-0.9.1 folder. Follow the rest of the compilation instructions from https://github.com/love2d/love/tree/0.9.1 (or this page) and see if you can build a new love binary file.
