I've seen a bunch of instructions and other references that mention editing a file called "options.ini". Where is this file supposed to be located? I can't find it anywhere.
It looks like you're new here. If you want to get involved, click one of these buttons!
On linux, it's in $HOME/.emptyepsilon
On windows, it should be in your EmptyEpsilon main directory, in the same folder where the file EmptyEpsilon.exe is located.
ON mac I do not know.
Also, that file is created at the first start. So it won't be present until you ran EmptyEpsilon at least once.
