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.

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.

No Watara Supervision emulator in Batocera needs a BIOS file to run.

Place your Watara Supervision ROMs in /userdata/roms/supervision.

RetroArch (formerly SSNES), is a ubiquitous frontend that can run multiple “cores”, which are essentially the emulators themselves. The most common cores use the 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] + South button (B SNES) which can be used to alter various things like RetroArch and core options, and 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
