Electron
The Electron is a computer developed by Acorn Computers. It was released in 1983.
This system scrapes metadata for the “electron” group(s) and loads the electron set from the currently selected theme, if available.

ROMs
Place your Electron ROMs in /userdata/roms/electron.
Requires MAME BIOS files electron.zip, electron64.zip, electron_plus1.zip, electron_plus3.zip Using software list mode (cassette) is recommended. Tapes should auto-load, use the MAME menu to stop/play/rewind if needed.
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: electron.videomode, electron.videomode, electron.ratio, electron.shaderset, electron.smooth, electron.integerscale, electron.bezel, electron.bezel_stretch, electron.hud, electron.bezel.tattoo, electron.bezel.tattoo_corner, electron.bezel.tattoo_file, electron.bezel.resize_tattoo, electron.ai_service_enabled, electron.ai_target_lang, electron.ai_service_url, electron.ai_service_pause, electron.runahead, electron.secondinstance, electron.video_frame_delay_auto, electron.vrr_runloop_enable, electron.video_threaded

MAME
MAME, the Multiple Arcade Machine Emulator, is a multi-purpose emulation framework which facilitates the emulation of vintage hardware and software. Originally targeting vintage arcade machines, MAME has since absorbed the sister-project MESS (Multi Emulator Super System) to support a wide variety of vintage computers, video game consoles and calculators as well. MAME doesn't use an individual “core” for each system like RetroArch does, instead the ROM itself usually contains the necessary information to accurately emulate it, thus making it specific to the version of MAME it was made for. Overall it's a very complicated subject, we have a guide specific to arcade just for it.
MAME configuration
MAME offers a Menu in-game ([HOTKEY] + or [Tab] on the keyboard). This can be used to manually adjust inputs or game settings. If you're having issues with a specific game, check the MAMEdev FAQ for that game here. For MESS systems specifically, you might find more information on MESS's wiki. All options can also be edited by opening the mame.ini file.
