===== 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: ''intellivision.videomode'', ''intellivision.ratio'', ''intellivision.smooth'', ''intellivision.shaders'', ''intellivision.pixel_perfect'', ''intellivision.decoration'', ''intellivision.game_translation''

^ ES setting name ''batocera.conf_key'' ^ Description => ES option ''key_value'' ^
^ Settings that apply to all cores of this emulator ||
| **GRAPHICS BACKEND ''intellivision.gfxbackend''** | Choose your graphics rendering\\ => OpenGL ''opengl'', Vulkan ''vulkan''. |
| **AUDIO LATENCY ''intellivision.audio_latency''** | Audio latency in milliseconds, turn it up if you hear crackles\\ => 256 ''256'', 192 ''192'', 128 ''128'', 64 ''64'', 32 ''32'', 16 ''16'', 8 ''8''. |
| **THREADED VIDEO ''intellivision.video_threaded''** | Improves performance at the cost of latency and more video stuttering. Use only if full speed cannot be obtained otherwise.\\ => On ''true'', Off ''false''. |

===== Controls =====
Intellivision had a complex controller with
  * 4 side-located action buttons (two for left handed players, two for right handed players). Top two side buttons are electronically the same, giving three distinct buttons.
  * a 12-button numeric keypad with plastic overlays that slide into place as an extra layer on the keypad to show game-specific key functions

It's therefore recommended to use a bezel from [[https://github.com/thebezelproject/BezelProject|thebezelproject]] to display those layouts, and to also display the game controller tattoo (available in ''V39+''). More information on [[https://wiki.batocera.org/decoration|decorations]].

The controller was often considered as a very bad one.

Here are the default Mattel Intellivision's controls shown on a [[:configure_a_controller|Batocera Retropad]]:
