Guys, give a try to the lr-scummvm libretro-based core for ScummVM I put for testing here: https://retropie.org.uk/forum/topic/19693/lr-scummvm-request-for-comments-and-testing/

You can do mappings via RetroArch and customise for each game too easily with RA. Also you can use any RA-supported shader. So far it has been working nice for me, would appreciate feedback from other ScummVM players.

Yeah I missed that. I read all my information from an old issue of MagPi. I did find that same info elsewhere.
