That's the guide I followed when I attempted the installation using Luma Plugin Loader and I'm not running BootNTR at all. I checked if I had any other .plg files anywhere on my SD card just in case something was messing it up and that is the only one there. I've used the files from GitHub when I was following that guide and followed every step stated. The Plugin Loader is booting up as already enabled on Rosalina however if I disable and then enable it again I get the whole green flash thing happen at that point which I'm not sure if it's meant to happen? The plugin works fine using the loader as long as I use the "sd:/luma/plugins/<Title ID of the game folder>/" but that is a bit of a hassle as means having to create new folders and mess around with the files which is why I'm hoping to get the "sd:/luma/plugins/ActionReplay/" to work.
