Mapping keys for games in Plex Arcade

After much effort, I finally got Plex Arcade to work with some of my Mame ROMs. I can’t, however, find any key mapping or way of changing them for each game. Is this possible?

I have been searching as well, I cant even figure out how to rotate on asteroids I can only shoot and accelerate. The only thing i found was in “AppData\Local\Plex Media Server\Plug-in Support” there is a RetroCores.xml and its contents have a section thats blank.

Key map can be found at Input and Controls - Libretro Docs. It is not possible to customize these.

That’s for adding your own game cores. https://support.plex.tv/articles/naming-and-organizing-game-files-and-cores/

If you don’t mind me asking, what file format do your MAME Roms use? I can’t get the library scan to recognize any MAME games I put into my games folder, tried .zip files, a folder named with the game and containing all of the uncompressed files, but no luck. Thanks!

have exactly the same problem - the arrow keys seem not to be mapped correctly. When I play the game on Chrome on mac or PC, there is no way to turn the ship in Asteroids. There’s also no way to move the cursor in Missile Command. It’s like the joystick mapping is completely missing. It works with my Logitech F710 gamepad, but only on PC, which isn’t helpful - i want to be able to play the games in a browser on my Mac, which is supposed to be supported. The other frustrating thig is that I can’t find how to delete the arcade subscription, i don’t want to pay $4/month for something i can’t use.

we’re fixing the mapping for e.g. Asteroids for the next release.
