| [[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 has [[emulators:retroarch|its own page]]. |
| | |
| === 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: ''atari800.videomode'', ''atari800.ratio'', ''atari800.smooth'', ''atari800.shaders'', ''atari800.pixel_perfect'', ''atari800.decoration'', ''atari800.game_translation'' | |

| ^ ES setting name ''batocera.conf_key'' ^ Description => ES option ''key_value'' ^ | |
| ^ Settings that apply to all cores of this emulator || | |
| | **GRAPHICS API ''atari800.gfxbackend''** | Choose which graphics API library to use. Vulkan is better, when supported.\\ => OpenGL ''opengl'', Vulkan ''vulkan''. | | |
| | **AUDIO LATENCY ''atari800.audio_latency''** | In milliseconds. Can reduce crackling/cutting out.\\ => 256 ''256'', 192 ''192'', 128 ''128'', 64 ''64'', 32 ''32'', 16 ''16'', 8 ''8''. | | |
| | **THREADED VIDEO ''atari800.video_threaded''** | Improves performance at the cost of latency and more video stuttering. Use only if full speed cannot be obtained otherwise.\\ => On ''true'', Off ''false''. | | |
