Standardized features available to all cores of this emulator: ''pet.videomode'', ''pet.padtokeyboard'', ''pet.videomode'', ''pet.ratio'', ''pet.bezel'', ''pet.bezel_stretch'', ''pet.hud'', ''pet.bezel.tattoo'', ''pet.bezel.tattoo_corner'', ''pet.bezel.tattoo_file'', ''pet.bezel.resize_tattoo''

==== RetroArch ====

[[https://docs.libretro.com/|RetroArch]] (formerly SSNES), is a ubiquitous frontend that can run multiple "cores", which are essentially the emulators themselves. The most common cores use the [[https://www.libretro.com/|libretro]] API, so that's why cores run in RetroArch in Batocera are referred to as "libretro: (core name)". RetroArch aims to unify the feature set of all libretro cores and offer a universal, familiar interface independent of platform.

=== RetroArch configuration ===

RetroArch offers a **Quick Menu** accessed by pressing ''[HOTKEY]'' + {{:wiki:south.png?nolink&20|South button (B SNES)}} which can be used to alter various things like [[:advanced_retroarch_settings|RetroArch and core options]], and [[:remapping_controls_per_emulator|controller mapping]]. Most RetroArch related settings can be altered from Batocera's EmulationStation.

Standardized features available to all libretro cores: ''pet.videomode'', ''pet.videomode'', ''pet.ratio'', ''pet.shaderset'', ''pet.smooth'', ''pet.integerscale'', ''pet.bezel'', ''pet.bezel_stretch'', ''pet.hud'', ''pet.bezel.tattoo'', ''pet.bezel.tattoo_corner'', ''pet.bezel.tattoo_file'', ''pet.bezel.resize_tattoo'', ''pet.ai_service_enabled'', ''pet.ai_target_lang'', ''pet.ai_service_url'', ''pet.ai_service_pause'', ''pet.runahead'', ''pet.secondinstance'', ''pet.video_frame_delay_auto'', ''pet.vrr_runloop_enable'', ''pet.video_threaded''
