 ===== Emulators =====
 ==== 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.

-In order to use this system instead, place your ROMs in ''/userdata/roms/videopacplus''. Most games were also backwards compatible with the original Videopac/Magnox Oddyssey2, to play games in this backward compatibility mode adjust the **ADVANCED SYSTEM SETTINGS** -> **MODEL** to FIXME or simply place your ROMs in ''/userdata/roms/o2em''.
-This system scrapes metadata for the "videopacplus" group(s) and loads the ''videopacplus'' set from the currently selected theme, if available.

 ===== Voice samples =====
 New to Batocera **v32**, a recent update to [[#libretro:_o2em|libretro: O2EM]] added sample support for emulating the voice synthesis module. Download the samples from [[http://o2em.sourceforge.net/|O2EM's homepage]] (hover over "Misc" near the top of the page) and extract them into ''/userdata/bios/voice''. Sid the Spellbinder requires its own pack, but if you're not intending on playing that game they're not required.

 ===== Controls =====
 The Magnavox Odyssey² used both a standard joystick controller with a single button and the built-in keyboard. The keyboard is already mapped to your default keyboard but most games utilized just the joystick.
