Emulators on LibreELEC

I have LibreELEC v8.95.2 running on a WeTek Play 2 and I installed a few NES and SNES emulators. When I go to the Add-ons menu there's nothing new there and under Games => Add-ons there's nothing at all. When I do the Konami code nothing happens. If I do it on my mini keyboard a window pops up saying I don't have a PVR installed. If I do the code on my PS3 controller it looks like it's trying to open the System menu but quickly goes back to where it started. Is there something else I'm supposed to install or configure? My PS3 controller seemed to work as soon as I paired it to the box so I never configured it and I'm not sure how. How do I actually get the emulators started? What am I missing? Any help would be appreciated.
