====== Watara Supervision ======

The Watara Supervision, also known as the QuickShot Supervision in the UK, is a monochrome handheld game console, originating from Asia, and introduced in 1992 as a cut-price competitor for Nintendo's Game Boy. It came packaged with a game called Crystball, which is similar to Breakout. One unique feature of the Supervision was that it could be linked up to a television via a link cable. Games played in this way would display in four colors, much like Nintendo's Super Game Boy add-on for the SNES. A full color TV link was also in the works, but because of the Supervision's failure to make a major impression among gamers it was cancelled, along with the games which were in development for it.

<WRAP center round info>
The system was renamed from ''watara'' to ''supervision'' prior to Batocera v31.

This system scrapes metadata for the "supervision" group(s) and loads the ''supervision'' set from the currently selected theme, if available.

===== 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.

Standardized features available to all libretro cores: ''supervision.videomode'', ''supervision.ratio'', ''supervision.smooth'', ''supervision.shaders'', ''supervision.pixel_perfect'', ''supervision.decoration'', ''supervision.game_translation''
