Othello Multivision
The Othello Multivision (オセロマルチビジョン) is a licensed SG-1000 clone designed by Sega and sold by Tsukuda Original. It exists because Sega's original intention for the SC-3000 computer was to allow other manufacturers to produce compatible computers in the hope of having a worldwide standard. Unfortunately, possibly with the emergence of the MSX, this tactic failed, and very few SG-1000/SC-3000 compatible machines were produced. The Othello Multivision was one of these machines.
This system scrapes metadata for the “multivision” group and loads the multivision set from the currently selected theme, if available.

Emulators
RetroArch
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] + 
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: sg1000.videomode, sg1000.ratio, sg1000.smooth, sg1000.shaders, sg1000.pixel_perfect, sg1000.decoration, sg1000.game_translation
