 ===== Emulators =====
+==== RetroArch ====
-==== libretro/mednafen_ngp ====
+[[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.
-Batocera uses the standalone port [[https://github.com/libretro/beetle-ngp-libretro|Beetle NeoPop]] based on Mednafen. Mednafen's Neo Geo Pocket emulation is based on NeoPop.
+=== RetroArch configuration ===
-===== ROMs =====
+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.
-Place your Neo Geo Pocket ROMs in ''/userdata/roms/ngp/''.
+Standardized features available to all libretro cores: ''ngp.videomode'', ''ngp.ratio'', ''ngp.smooth'', ''ngp.shaders'', ''ngp.pixel_perfect'', ''ngp.decoration'', ''ngp.game_translation''
+^ ES setting name ''batocera.conf_key'' ^ Description => ES option ''key_value'' ^

+=== libretro: Mednafen_ngp ===
+Batocera uses the standalone port [[https://github.com/libretro/beetle-ngp-libretro|Beetle NeoPop]] based on Mednafen. Mednafen's Neo Geo Pocket emulation is based on NeoPop.
