[BUG]bluetooth controller can't access retroarch menu

[Andpang]

I connected a Bluetooth controller, set the Bluetooth controller to player 1, played some games, pressed the hotkey to go to the RetroArch menu using the Bluetooth controller, and the Bluetooth controller can't be used in the RetroArch menu? I pressed up and down but it didn't have any effect.
(I use anbernic RG353p)

Sounds like a controller not supported by retroarch. Either use a supported controller or submit a PR rocknix with a controller profile for your device.
