| [[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: ''3do.videomode'', ''3do.videomode'', ''3do.ratio'', ''3do.shaderset'', ''3do.smooth'', ''3do.integerscale'', ''3do.bezel'', ''3do.bezel_stretch'', ''3do.hud'', ''3do.bezel.tattoo'', ''3do.bezel.tattoo_corner'', ''3do.bezel.tattoo_file'', ''3do.bezel.resize_tattoo'', ''3do.ai_service_enabled'', ''3do.ai_target_lang'', ''3do.ai_service_url'', ''3do.ai_service_pause'', ''3do.integerscale'', ''3do.runahead'', ''3do.secondinstance'', ''3do.video_frame_delay_auto'', ''3do.vrr_runloop_enable'', ''3do.video_threaded'' | |

| | **GRAPHICS BACKEND ''3do.gfxbackend''** | Choose your graphics rendering\\ => OpenGL ''opengl'', Vulkan ''vulkan''. | | |
| | **AUDIO LATENCY ''3do.audio_latency''** | Audio latency in milliseconds, turn it up if you hear crackles\\ => 256 ''256'', 192 ''192'', 128 ''128'', 64 ''64'', 32 ''32'', 16 ''16'', 8 ''8''. | | |
| | **THREADED VIDEO ''3do.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''. | | |

| Opera is an open-source, low-level emulator for the 3DO Game Console. Opera is a fork of 4DO, originally a port of 4DO, itself a fork of FreeDO, to libretro. The fork/rename occurred due to the original 4DO project being dormant and to differentiate the project due to new development and focus. | Opera is an open-source, low-level emulator for the 3DO Game Console.
