Thank you, robmcc83 I got it playing SNES roms via AEL/Retroplayer. The whole process was confusing, at least for a newbie like me who's missing a lot of context.
Also had to mess around for a bit to get my no-name PS3 compatible controller to work correctly in-game. Not that it works flawlessly with the LE interface either...
No artwork for now, as it's looking to take too much effort.
I'll see about geting the PSX roms to work, this one has the added complication of having to supply as bios as well..
Ok so regarding the bios this to is also simple.
I use gamestarter repo with retroarch and this is how I do it.
I use lakka website for reference of which bioses I need for the systems I use just Google lakka bioses. The version of retroarch in lakka is the one that is compiled for our gamestarter repo.
Now all you have to do is get hold of the bioses the lakka recommends again Google will help with this.
Then over samba or sftp/FTP login into your libreelec, From there your looking for directory /storage/emulators.
If you have already loaded up retroarch it will have created 3 folders. bios,roms and saves.
Just copy the bios files you have obtained from the internet to the bios folder and that's it happy psx gaming.
